1. Principal × percent interest = interest earned

Principle× (0.075)× 1/(12 x 4) = $68. Solve to find the principal (68 × 12 x 4)/0.075=
$43,520. The correct answer is D.

2. Use the factors of 120 are: 1x120, 2x60, 3x40, 10x12, 4x30, 5x24, 6x20 and 8x15.

We are looking for combinations of (row x column) that are all between 8 and 30.

The possibilities are: 8x15, 15x8, 4x30, 30x4, 5x24, 24x5, 6x20, 20x6, 10x12 and
12x10. That is 10 possibilities total. The correct answer is E.

3. The total estimated amount that will be spent on type A product next year:
5625$
1001254500$=×.
The total estimated amount that will be spent on type B product next year:
9130$
1001108300$=×.
Giving a total spending of $14,755. The correct answer is A.

4. The side of a cube equals the cubic root of its volume; in this question it is 4. The
lateral area of a cube equals the sum of four faces; in this question each face is 16, and
the lateral area is four times that, giving 64. The correct answer is B.

5. The fact that X is divisible by 7 does not help figure out whether it is odd or even,
both even and odd numbers could be divisible by 7. The same applies for 11; both
even and odd numbers could be divisible by 11. Both statements taken together do not
shed a new light on the matter, there could be even and odd numbers that are divisible
by 7 and 11. The correct answer is E.

6. The prime factors of 22 are 2 and 11. Hence, if X is divisible by 4, it is divisible by
2 and if Y is divisible by 11, surely XY is divisible by 22. The correct answer is C.

7. Since three digits are zero, only 4 digits are left for consideration (of which, none is
zero). Since 1 does not appear in the numbers, there are 4 even numbers (without 0),
and 4 odd numbers (without 1) to choose from. The probability for every digit to be odd is
21. There are 4 different ways to arrange 3 odd numbers and one even number
in 4 places. Each of these ways has a probability of ()214. And together:
()16416144214=×=×. The correct answer is D.

8. From 8:00 am to 9:00 am, Pipe A, which fills the pool in 4 hours, was open for one
hour, filling one quarter of the pool. From 9:00 am, the two Pipes worked together at
the rate of:
1216141=-, one pool in 12 hours. Since the pool was already one quarter
full at 9:00 am, it will take only 9 hours to fill the remaining three quarters of the
pool. 9 hours from 9:00 am is 18:00. The correct answer is C.

9. Since a2-b2=(a+b)(a-b), 133=(a+b)7, and (a+b)=19.

Both statements are needed to solve the question. The correct answer is C.

10. Each statement alone leaves out one of the terms x or z, so we cannot find their
sum using any statement alone. Moreover, even combining both statements does not
help:

1113xzz13x11z13yx 11y13yz 11yx-=-
-=-
-=-=
=+=+
It is only possible to find z-x. The correct answer is E.

11. Knowing the interest alone is not enough to calculate the profit.

Knowing the total amount invested is not enough to calculate the profit, unless we
have the interest rate.
Since we have no knowledge of the amount invested in each investment, there is no
way to know how much was earned. The correct answer is E.

12. The only two possible sets that have 4 different positive integers and an average of
3 are: [1, 2, 3, 6] and [1, 2, 4, 5]. The sum of the two smallest integers in both sets is
always 3. The correct answer is C.

13. If X is the number of students in the largest class, then the numbers of students in
the other classes are: X-2, X-4, X-6 and X-8. The total number of students is:
958)(X6)(X4)(X2)(XX=-+-+-+-+ and 23X1155X95205X=.=.=-.
The correct answer is D.

14. Take 40 litters as the volume of the large container to ease the calculations. Of this
volume, 20 litters are ice cream. The volume of the second is 20 litters and 15 litters
are ice cream. So, the total volume of both containers is 40+20=60, and the ice cream
is 20+15=35. Now,
1276035=. The correct answer is B.

15. Solve a combined average problem: 8%
X)(480%X10%48=+
×+×. The correct
answer is B.

16. The average age of both groups, x and y was n five years ago. Therefore, it is
possible to treat them as one group with that average. Five years later, each student
added 5 years to his age, adding 5 to the average of the whole class, and making it
n+5. The correct answer is: A.

17. The rate of the “racing magic” is 40 rounds per hour, or 1 round every 1.5
minutes. The rate of the “Charging bull” is 1 round every 120 seconds, or 1 round
every 2 minutes.
The best way to solve such a question is to find the least common denominator
between the two rates. At that point, they will meet for the first time, and when
multiplied by 2, we find the second time they meet:
64631.5121.=.. They will
meet for the first time after 6 minutes and for the second time after 12 minutes. The
correct answer is D.

18. The first statement gives no information of the number of cookies. The volume of
the carton box or the percent of its volume filled, do not help in finding any number.
The second statement gives all the information needed in order to find the number of
cookies packed in each carton box. The number of cookies per jar, and the number of
jars per box are sufficient to calculate real numbers. The correct answer is B.

19. In order to find the value of a term in an equation with two unknowns, two
different equations are needed. Since both equations given in statements 1 and 2 are,
in fact, the same equation in a different shape, it is impossible to find the value of X
or Y. 2X3Y3119Y46X=-.-=. The correct answer is E.

20. After spending one quarter of the budget on rent, 75% is left, of that half = 37.5%
is spent for food and beverages. The correct answer is D.

21. Compare x oranges to y peaches at the price of 24 cents per peach. Divide by 100
to receive the amount in dollar:
x100y24O10024yOxPeachesyOrangesx=.=×.×=×. The correct answer is D.

22. Compare the volumes: 3333331RrRr3Rp34rp343=.=×.=×. The correct
answer is A.

23. Since x=y and both are primes,
yx11+could equal 32 when x=y=3, or equal 1
when x=y=2. Therefore, the first statement is not sufficient to solve.
According to the second statement, x+y=4, the only primes to match are x=y=2. Now
we know that yx11+=1 and the question is solved. The correct answer is B.

24. Statement (1) tells us that the diameter of the ball is the height of cube, so we can
find its volume.
Statement (2) actually tells us that the box is a cube, and the rest is similar to
statement one. The correct answer is D.

25. Statement (1) can provide us the height of the cylinder while statement (2) gives
us data we already can conclude from the question. The correct answer is A.

26. The car travels 160 miles in 160 minutes, that is 1 mile per minute. So, it travels
60 miles in 60 minutes, or 60 miles per hour. The correct answer is B.

27. . And x=5. The correct
answer is: E.
186X7)X42221618X67)X418X67X+=+.=.=++++((

28. First find z: z+5+7=16, therefore, z=4. Now, y+4+5=7 making y=(-2). Now we
can find x: x+(-2)+4=5, so, x=3. Hence, x+y=3+(-2)=1. The correct answer is: C.

29. John spends a sum of m dollars and still has m-800 left. So, m+m-800=1,600, and
m=$1,200. Therefore, John still has $1,600-$1,200=$400. The correct answer is B.

30. Calculate the odds of not winning first, second or third prize by deducting the
chances of winning first, second or third from 1:
200193501100120011=..
.
..
.++-. The
correct answer is: C.

31. The red painted area is 3 half faces and the white painted area is a total of 9 half
faces. The ratio is, therefore, 1 to 3. The correct answer is: E.

32. Statement (1) defines the relationship between X and Y.

Statement (2) defines the relationship between Y and R.

We get the following equations:

10 x X + R x Y = 12 (X+Y), Y=X+5, and Y=R. Now solve and find R. The correct
answer is C.

33. Since we don’t know how many children there are at all, it won’t help us to know
the relationship between the child who left and the shortest child.

Statement (2) defines the connection between the sum of the heights before and after
the departure and using the change in the sum divided by the new number of children
we can find the number of children. The correct answer is B.

34. Since we have no concrete info about the exact heights, or about the value of P
and R, we cannot determine whether the NBA players or the weight lifters are taller.
We need more data. The correct answer is E.

35. Statement (1) can tell us the value of Y, and the value of X, which is enough to
solve this problem.
Statement (2) alone only defines the connection between X and Y. The correct answer
is A.

36. Two out of every 10 damaged light bulbs have a broken glass, so if 20 bulbs have
a broken glass, there are 100 damaged light bulbs. Since one out of every 500 is
damaged, there are light bulbs in the shipment. The correct answer
is D. 00050500100,=×

37. Since the even number a is raised to the power of 3, it is always divisible by 8.
Therefore, the whole expression must be an integer, an even or an odd one. Of course,
the expression cannot be a fraction. The correct answer is E.

Answers and Explanations to Test 2

2009-08-20T04:25:00.001-07:00

1. The fastest way to solve this problem is by plugging in some numbers.

Lets say: X = 2, Y = 1.

According to answer e: 1 x 1 = 1 and that must be an odd number.

The correct answer is E.

2. Here, it is enough to calculate the simple interest of 8% per year.

$2,400 x 8/100 x 1 = $192. Since we are calculating as a compounded rate, the
interest should be a bit higher, or C as the correct answer.

3. Statement (1) alone is insufficient since there is infinite number of possibilities.

Statement (2) alone is insufficient since there is an infinite number of primes.

The combination of the statements is sufficient since the only even square of a prime
number is can be 22, which is 4. Both statements, taken together, are sufficient. The
correct answer is C.

4. Statement (1) alone is insufficient since we need the value of A + 2B.

Statement (2) is sufficient. A2B = A(AB) = A(40) = 80 .. A=2 and B=20.

Now, we know that A + 2B = 42 and we can calculate the required expression.

The correct answer is B.

5. Statement (1) is insufficient since the expression given is only one of two needed.

Statement (2) by itself is sufficient since X3Y2 = (X3Y)Y = 24Y = 72 .. Y = 3.

If Y=3 then X3=8 and so X=2.

The expression required is a combination of X and Y and is then calculable.

The correct answer is B.

6. Because X is a prime number bigger than 10, it must be odd. Ignoring the powers
of X in the expression of Y, you’ll see that Y is a sum of 4 odd numbers therefore it
must be even. The correct answer is C.

7. Find the sum of the first 4 primes larger than 20: 23+29+31+37=120. The correct
answer is C.

8. The best way is to take an example: Assume x=2 and y=10, then their average z=6.
The average of x=2 and z=6 is w=4. Therefore:
316210442=
-
-
=
-
-
=
-
-
ywwx. The correct
answer is B.

9. First, calculate the fraction of the 25 managerial workers out of the total number of
workers by subtracting the fractions given from 1.

2012019120104512151411=-=
++
-=---.

The 25 managerial workers are
201of the workers, therefore, 5002025=×, a total
number of 500 workers. The correct answer is D.

10. This statement is equivalent to 0.8sb – sa = 3sa. The income is 0.8sb, the cost is
sa, so the profit is three times the cost.

The correct answer is A.

11. From (1) we have X and Y and therefore we can find A easily, A = 300.

(2) Is identical to (1), simplify it and see that it can be written as X = 3Y.

Either statement by itself is sufficient. The correct answer is D.

12. The easiest way to solve such a problem is to plug in numbers.

Use both statements to see that they are both insufficient even together.

Take X=0: 1/(5 – X) = 1/5 and X/5 = 0, in this case the first expression is larger.

Take X=7: 1/(5 – X) = -1/2 and X/5 = 7/5, in this case the second expression is larger.

We can see that the answer is dependent on which numbers we choose and more data
is required in order to determine the answer. The correct answer is E.

13. There are a limited number of possibilities: 21, 42, 63 and 84.

According to statement (1), the only number that is compatible is 63.

According to statement (2), the only number that is compatible is also 63.

Either statement alone is sufficient. The correct answer is D.

14. The total income is 16x200. The cost is 24X, and the total profit is 3200 – 24X =
48X. The correct answer is C.

15. X is Kenny’s age. X/3 is Bob’s age. Answer C is equivalent to (X+P) =
2(X/3+P+Q), which means that in P years, X+P is 2 times (X/3+P) plus Q years. The
correct answer is C.

16. Sign the French cigar as X. The Cuban cigar is 1.5(X-0.7) - 1.

The Arabian cigar is 1.5[1.5(X-0.7)-1] + 0.5.

The sum of all the three is 74.7. The correct answer is A.

17. One notebook can cost 1, 2, 3 or 4 dollars. Subtract 15 times each price from 93,
and check if what you get is divisible by 5 minus the price of the notebook. The
number could be 24, 21 or 33. The correct answer is D.

18. Statement (1) can be written as: Y = 2X + 54.

Statement (2) can be written as: X = 3Y – 72.

Combining both statements, we have two different equations containing X and Y and
so we can solve and find the value of X and Y and calculate what is X percent of Y.

The correct answer is C.

19. Statement (1) is all about the windows and therefore it is not sufficient by itself.

Statement (2) tells us that Q + W/2 = 12, this is sufficient because the total price of
windows and shelves is 150Q + 75W.

Multiply the data in statement (2) be 150 to get: 150Q + 75W = 18,000.

Statement (2) is sufficient by itself.

The correct answer is B.

20. The question tells you that the area is 60, the area of a rectangle is equal to length
x width, in order to find the perimeter, one should find the value of the length and the
value of the width.
Statement (1) tells us that both the length and the width are even integers and
therefore we know their exact values because 60 can be factorized to: 1x60, 2x30,
3x20, 4x15, 5x12 and 6x10.
The only even integers smaller than 25 are (6x10) and we know the perimeter.
The correct answer is A.

21. Statement (1) tells us that 9X2 is an even number (it’s divisible by 4) and therefore
X2 must be an even number. An odd number squared is also odd and therefore X must
be even, this statement is sufficient.
Statement (2) tells us that 3X + 2 is an even number (it’s divisible by 8).
If you subtract 2 from (3X+2) the result will still be even. If 3X is even than X must
be even. This statement is also sufficient to answer the question. The correct answer is
D.

22. Changing the equality: 22X + 24Y = 160, we get: X
Since X must be a positive integer, Y must be smaller than 7. The numerator will be
11, 22, 33, 44 etc. Y must be 3 and X=3. X+Y = 7. The correct answer is C.

23. D shows us the difference between the sum of the percentages and 100 percent. If
X+Y>100, this percent must be subtracted from the sum X+Y in order to get 100
percent. Sum of sets minus the total equals the congruence. The correct answer is D.

24. The buying price for one car is 1,105,000 / 13 = 85,000.The wished for a car is
39,000 / 13 = 3,000. So the selling price must be 85,000 + 3,000. The correct answer
is B.

25. 5% of the total price of the cloths is 45.5 dollars, multiply this number to get the
entire 100% of the total selling price: (45.5 x 20 = $910). Now subtract the profit
$45.5 to get the cost: 910-45.5=$864.5. The correct answer is E.

26. Statement (1) tells us that 9X2 is an even number (it’s divisible by 4) and therefore
X2 must be an even number. An odd number squared is also odd and therefore X must
be even, this statement is sufficient.
Statement (2) tells us that 3X + 2 is an even number (it’s divisible by 8).
If you subtract 2 from (3X+2) the result will still be even. If 3X is even than X must
be even. This statement is also sufficient to answer the question.

27. In order to know how many people aren’t officers you need a fix value, in other
words you need to translate percentage into real values.
Statement (1) doesn’t give any real numbers and therefore it’s not sufficient.

111280Y

Statement (2) is the same as one in that matter, if we wanted to know the percentage
of the woman officers, the statements would have been satisfying. More data is
required. The correct answer is E.

28. 65X/100 is the number of people who didn’t win the tender. 30% of that number
is the number of people who weren’t deeply disappointed about the fact that they
didn’t win. 30 x (65X/100) /100 = 19.5/100 = 39/200. The correct answer is A.

29. Since 0.01 and 0.03 each have 2 decimal places, their product must have 4 (2 + 2)
decimal places. Because 1 x 3 x 5 is 15, you need to add 2 zeros to get the correct
number of decimal places, so the product of 0.01, 5 and 0.03 is 0.0015. To change a
decimal to a percentage you multiply by 100 and move the decimal point 2 places to
the right, so 0.0015 is 0.15%. The correct answer is C.

30. Pick numbers: a barrel of beer costs $40 and a barrel of juice costs $30 according
to the given ratio. One liter of beer will cost $0.5 and one liter of juice will cost $1.
Therefore the price ratio is 2:1. The correct answer is B.

31. Statement (1) tells you that X is greater than X2, that is true only if X is between
zero and one and so the answer to the question is no.

Statement two is identical to one, multiply both sides by (-1) and don’t forget to
change the sign of the inequality. Either statement is sufficient by itself. The correct
answer is D.

32. From statement (1) we have only one set of numbers. We have 5, 6, 7, 8, 9, 10
and 11.
Statement (2) provides no additional data because we can see several sets containing
7. The correct answer is A.

33. Statement (1) tells us that 2M3 + 2M is divisible by 8 and so M4 + M is divisible
by 4 and is even. We have two choices: M3 and M are either odd or even. This
statement is insufficient.

Statement (2) is sufficient, if M + 10 is divisible by 10 then M + 10 is an even
number. This statement is sufficient and the answer is B.

34. One is going north and the other is going west. The distance can be calculated
using the Pythagorean theorem. One made a distance of 1.6 x 5 = 8 Km, The second
one did 1.2 x 5 = 6 Km. The distance between them is the square root of (64 + 36) =
10 Km. The best answer is A.

35. George can fill Q/3 cans of paint in one minute .. There are R cans in one gallon,
so R/(Q/3) = 3R/QIs the time it takes George to fill one gallon (in minutes). In 45
minutes George can fill up 45/(3R/Q) = 15Q/R. The correct answer is E.

36. Plug in the answers.

(a) (4 # 2) = 8. The answer should be 14.

(b) (2 # 3) = (2 + 3)3 = 15. The answer should be 6.

(c) (2 # 3) = (22 – 3) = 1. The answer should be 6.

(d) (4 # 2) = (42 – 2) = 14. This is the right answer; check (2 # 3) also.

The correct answer is D.

37. Draw the x and y-axes, then plot the points and connect them.

The area of a trapezoid is (base1 + base2) x (height) / 2.

Base1 = 5, base2 = 4, height = 18 thus the area is 9 x 9 = 81.

The answer to the question is the square root of 81, meaning 9.

The correct answer is B.

Answers and Explanations to Test 1

2009-08-20T03:30:00.000-07:00

1. Translate piece by piece into numbers. R (Roy) = Erik (E) + 4. The second equation: R = I (Iris)+ 2. The third equation: R +7 = 2(E + 7). We have three equations with three variables. Roy is 6, Iris is 4 and Erik is 2. In four years Erik would be 6 and Iris 8, the answer is 48. The correct answer is C.

2. Principal × percent interest × time = interest earned Principle × (0.09)× 1/12 = $228. Solve to find the principal (228 × 12)/0.09= $30,400. The correct answer is B.

3. The first expression is even and the second is odd, the only difference between the expressions is that the first expression has X and the second has W. So, if X is even W must be odd and the correct answer is C.

4. The area of the triangle is XY/2. Statement (1) tells us that X is a prime number, that can be even (2) or odd (3, 5, 7, etc.). Statement (2) tells us that Y is an odd integer. The multiplication of X and Y can be an odd number or an even number, thus we cannot determine if the area of the triangle is an integer or not. The correct answer is E.

5. Statement (1) is insufficient since the size of the reservoir is irrelevant. Statement (2) is sufficient since it tells us that the second tanker has the same work rate as the first. So, it will take them both half the time it took the first tanker alone. The correct answer is B.

6. 3Q is a prime number so it can be divide equally by 3Q, by 1 and by the components 3 and Q. The smallest number therefore is 3. The correct answer is C.

7. The number of green and yellow balls in the box is A+2. The total number of balls is 4A +8. The probability of taking out a green or a yellow ball is: 41842=++AA. The correct answer is D.

8. The price of the ticket is unknown. It would be most convenient to plug in 100 as the price of the ticket. A 30% discount of 100 is $30, that amount remained the same after the price of a ticket increased by 50%. The new price of a ticket is $150, so 30/150 is 20%. The correct answer is B.

9. If you square each digit {0, 1, 2,..., 8, 9}, you will see that the possible last digits for a square are 0, 1, 4, 5, 6 and 9. Thus, if the last digit of A is 8, A cannot be a square and the square root of A is not an integer. Statement (1) by itself is sufficient. Statement (2) by itself is insufficient since there are numbers that are divisible by 6 and have an integer square root and numbers divisible by 6 that do not have an integer square root. The correct answer is A.

10. We want to find the number value of Q. In statement (1) we are given the ratio between Q and T, which is not sufficient. Statement (2) can be simplified: 277277214774)2(727QTQTQTQT=⇒+=+⇒+=+⇒+=+. We can see that the same ratio is given in statement (2) also and more data is required to answer the question. Both statements give the same information. The correct answer is E.

11. From the grade 40 at the end of the first year we learn that his age is 20. At the end of the second year, he will be 21 and his grade will be (21 x 2 + ½ x 40 = 62). At the end of the third year, he will be 22 and his grade will be (22 x 2 + ½ x 62 = 75). The correct answer is D.

12. Factorize C: C = A x A x A: C can be equally divided into 1, A, A2, and A3 =C 4 numbers total. The correct answer is B.

13. Find the factors of (405) 4 and see what the largest value of X can be. 405 = 81 x 5 = 9 x 9 x 5 = 3 x 3 x 3 x 3 x 5 (405) 4 = (3 x 3 x 3 x 3 x 5) 4 = 316 x 54. The largest possible value of 3X that is still a factor of (405) 4 is the largest possible value of X and that is 316. X = 16. The correct answer is C.

14. Statement (1) is sufficient. If X2 is a fraction, X must also be a fraction. Meaning that X3 and Y will also be fractions. Statement (2) is sufficient. If X3 is a fraction then X must be greater than X3, which is also equal to Y. We get that from X > Y, so X3 and Y are fractions.
The correct answer is D.

15. Statement (1) gives us the average speed of the turtle; this statement is insufficient since the time is not given.
Statement (2) is also insufficient by itself since we don’t know what the average speed is.
Both statements combined are sufficient since we can calculate the distance
2*T=D and 3(T-40)=D, solve to get D=240 meters. The correct answer is C.

16. We are told that the stock increases its value by a constant rate and therefore we need to find some kind of pattern in order to know the value every year.
Statements (1) and (2) taken together are sufficient since they give us the percent increase of the stock from 1991 to 1992, which is 15%. The value of the stock in 1998 can be easily calculated, add 15% every year until 1998. The correct answer is C.

17. Answer D is a multiplication of two consecutive numbers, therefore one of them must be even, and an even number multiplied by a different number is an even number. The correct answer is D.

18. 25,200 x 1.1 = 27,720. 27,720 x 0.9 = 24,948. The correct answer is C.

19. Dividing the requested amount of miles by the reference amount would give us the answer in inches. 383.6 / 28 = 13.7 inches. The correct answer is C.

20. The total working days for finishing a web page are (15 x 3) 45. If after one day 9 programmers quit, only 15 working days are done and the rest of the programmers (6) Need to finish (45 – 15) 30 days of work. It will take them 5 more days. The correct answer is C.

21. Tim is traveling at twice the speed of Élan, and so will be after they double their speeds. The ratio between their velocities will always be 2:1 and the ratio between the distances they will pass will also be 2:1 or 60 miles to 30 miles. Tim will go through 60 miles. The correct answer is D.

22. In order to calculate the time it would take to complete one rotation, you need the radius and the velocity. Statement (1) provides the radius of rotation and (2) provides the velocity.
The distance the spaceship has to travel in order to complete one rotation is )000,21(22⋅⋅=⋅⋅ππR and the speed is 35 miles per second. Divide the first by the second and you’ll get the time it would take the spaceship to complete one rotation.
The correct answer is C.

23. Since we need to compare between X and Y, look at both statements together.
(1) and (2) state that: 12X = 4C = 12Y4 X = Y4.

Take Y=-1, X=1: X is bigger than Y.
Take X=1 and Y=1: X is not bigger than Y.
The answer is not distinct and therefore more data is required in order to solve the question. The correct answer E.

24. If a circle inscribers a square then the diagonal of the square is the diameter of the circle, which is sufficient to find the perimeter.
Statement (1) tells us about the square that is inscribed with out any further data.
Statement (2) gives us the perimeter, which is equal to 4 times the side of the square.
If we know the side of the square, we know its diagonal.
Both statements, taken together, are sufficient. The correct answer is C.

25. Draw the x and y-axes, then plot the points and connect them. The length of the base is 6 units [from (6, 3) to (6, -3)] and the height is 2 units [from (6, 0) to (4, 0)].
Area of a triangle = (base × height) / 2, so (6 × 2)/2 is 6. The correct answer is D.

26. [6.5] x [2/3] + [2] x 7.2 + [8.4] – 6.6 = 6 x 0 + 2 x 7.2 + 8 - 6.6 = 15.8. The correct answer is C.

27. ()()0.001610161021025144444=×===−. The correct answer is E.

28. The first digit has 7 possibilities (10 – 0,3 and 6). The other three digits have 8 possibilities each. 7*8*8*8= 3584. The correct answer is B.

29. From (1) by itself we can only learn that 90 kids have good grades. This statement is insufficient.
From (2) we can learn that there are 100 girls in the group.
Combining the statements doesn’t help much since we know nothing about the overlapping of (1) and (2) and more data is required. The correct answer is E.

30. Statement (1) tells us that 10 cans cost 4.2 dollars instead of 5 dollars and therefore the last two cans were sold for 20 cents. This statement is sufficient.
Statement (2) also tells us that the entire amount of cans cost 4.2 and therefore this statement is also sufficient. The correct answer is D.

31. From (1) we know the value of Y only, which is 1.
From (2) and (1) we know the value of all the other parameters, X = 4 and ZW = 4.
Therefore, (1) and (2) together are sufficient. The correct answer is C.

32. The phone company already created 122*122 area codes, now it can create 124*124. 1242-1222=(124+122)(124-122) = 246*2 = 492 additional codes. The correct answer is C.

33. If the average of 7 numbers is 12.2, we can solve for their sum: 7 × 12.2 = 85.4. If four of these numbers total 42.8, then by subtracting 42.8 from 85.4, we get the sum of the other three numbers, 42.6. To find the average of these three numbers, we divide their sum by their number: 42.6/3 = 14.2. The correct answer is B.

34. Statement (1) is insufficient. Take A=0 and B=0, (1) is correct yet A4 is not bigger than B4.
Take different numbers, A=6 and B=12 A4 is larger than B4.
Statement (2) is sufficient. The only possible way that A will not be larger than B is if they are both zero. (2) Claims that A <>

35. Lets look at two cases, where each one will give out different results. One of the numbers is 15 and three more are 15, 15 and 15 (with an average of 15). The sum of all the numbers should be (20 x 5 = 100). The sum of the numbers we picked up is (15 x 4 = 60) and therefore the last number should be 40 which is greater than 15. The answer in this case is 1. Take another case: One of the numbers is 15 and three more are 14, 15 and 16 (with an average of 15). In this case there will be 2 numbers over 15. More data is required. The correct answer is E.

36. Getting three red out of 4 that are taken out has 4 options (4!/(3!*1!)) each option has a probability of (1/2)4 since drawing a red or blue has a 50% chance. 4*1/16= ¼ to get three red hats. The same goes for three blue hats so ¼+¼ =1/2. The correct answer is C.

37. (2X + Y)(2Z + W) = 4XZ + 2XW + 2ZY + WY. Now, plug in this data to get: 3 + 2 x 6 = 15. The correct answer is C.

Aptitude Test Format II

2009-01-21T00:06:00.000-08:00

FIDELITY BANK
It consists of verbal and quantitative reasoning questions. The Maths questions are easy and the Verbal questions are just passages, sentence completions and the likes. Read your GMAT 2007 or anyone and you are good to go.
FIRST BANK
that they have 100 questions. But the time is very short.
The first part is a long comprehension, which one could possibly spend at least 15 minutes on. It has only 10 questions. This part is time consuming, avoid starting on this part. People who started on the first section didn’t finish up to 60 questions at the end of the test.
The second part is English (Verbal reasoning). It requires a bit of thinking, although its fairly easy. Don’t start here as well.
The third part is Math. They are simple as well, but the chances are that you might spend over 1 minute working out each answer. If the format is as before, you are also adviced not to start with this.
The forth part is on Current Affairs, with a multiple answer style. This is easier and you spend lesser time.
The fifth (final) part is on Critical reasoning. This is also very easy.
It is a maximum of 60mins or 80mins. You will only use writing materials like pencil, cleaner and maybe a pen.
Calculators are usually not allowed and you will be provided a plain sheet to work out your answers.
GUARANTY TRUST BANK
their test format is in three parts. You have Verbal Reasoning, Numerical Reasoning and Grahical Interpretation. All they need is your accuracy how u can think on the spot.They are usually simple questions but the challenge is you have 24mins for 80 questions. So you have to be fast in thinking.
STANBIC IBTC
It is more of GMAT. About 20 GMAT Mathematics and English. Some ‘Nearest in meaning’ English as well and you will be asked to work some mathematics without options i.e. no multiple-choice objective in them. know the meaning of words like-loquacious,poignantly,avarice,
INTERCONTINENTAL BANK
Their format is GMAT. It contains Maths and English. 100 questions. Go and look for IEC Gmat text book:2004 edition. I heard it is scarce in the market. If you get the text book, craM all the questions and answers. All their question were lifted from there.(Word for Word)
Cut off is 80%
OCEANIC BANK
Oceanic bank test is 70 questions to be answered in 60 minutes. 15 Maths, Comprehension 10, Grammar 20, Current affairs 15 and business questions 10. Just relax and put in your best. Pass mark is 50% which is 35 out of the 70.
SKYE BANK
The test format is 80 questions comprising Maths, Verbal Reasoning, Spatial Orientation, Lateral Reasoning and 1 essay. all in 1hr 15mins.
SPRING BANK
Their questions are usually from G-Mat, practice your G-mat, 2003,2004,2005,2006, infact any G-mat at your reach because that is where their questions usually come from. Meanwhile its always English and Mathematics.
UBA
Just read your GMat. Then also have an idea bout current affairs, e.g. Who’s d senate president, when was nations/africans cup played and in which country, Who’s Bank PhB’s MD(sounds strange for UBA, right?)
The test is simple: Maths, English and Current Affairs. Maths is 15 questions, English is 15 questions, Current Affairs is 20 questions.
ZENITH BANK
the format is thus: Numerical Reasoning, Comprehension, Sentence Correction and Critical Reasoning. There are 100 questions and 2 hours to finish up. If you can get Barrons foreign GMat. They dub their questions from foreign GMat. Both the comprehension, critical reasoning, and the rest. The questions will be very voluminous and you have to read fast.
Well don’t have the format for Afribank, First Inland, Stanbic, Sterling, Union, Unity and Wema Banks. Please post them here if you have. Thanks

Aptitude Test Format I

2009-01-21T00:01:00.000-08:00

Aptitude tests are designed to measure your intellectual capabilities for thinking and reasoning, particularly your logical and analytical reasoning abilities. They aim to assess your abilities to use specific job-related skills and to predict subsequent job performance. The most commonly used tests assess verbal and numerical logical reasoning skills; other types of test will also assess your diagrammatic reasoning skills.

Below are a range of practice aptitude/ability test sites for you to try out, either in preparation for the real thing or just to find out more about yourself and your abilities.

ASE-solutions.co.uk - access ‘Graduate and Managerial Assessment’ for practice aptitude tests.

Shldirect.com - practice aptitude tests from one of the UK’s largest test publishers.

Morrisby - examples of ability tests found in the Morrisby Profile tests.

Graduate Management Admission Council - for graduates interested in applying for MBA courses.

Educational Testing Service - gives access to practice questions for GMAT, GRE and the Test of English as a Foreign Language (TOEFL).

Saville Consulting Aptitude Assessments - advice on preparing for aptitude assessments.

Saville Consulting Wave Professional Styles - questionnaire measuring motivation, talent and preferred culture.

ACCESS BANK
The test is made up of two papers, 50 questions each and you are expected to make at least 50% in each (25marks). Its a combination of Maths, English, Critical Reasoning and a little bit of Current Affairs (States and Capital).

BANK PHB
I think the test is administered by Leading Edge Consult and it is basically a combination test comprising about 70 questions on different test areas: Verbal, Synonyms, Antonyms, Word analogies, Basic arithmetic, Shape comparisons, Mirror images of wall clocks & other stuffs. There are no options in many of the questions. I think the time is 50 mins or 1hr.I can’t remember exactly.
Bank Phb test is very difficult. The good thing about it is that cut off mark is as low as 30%.

CITIBANK
The test is a booklet in 3 sections. A, B ,C , Maths (mostly Tough Fractions),Like 2/3 + 4/7 all over 7/8 - 5/7 = 5/4 -6/5 then Logic like these vivid ones:
1. A gave hand shake to B; and B gave hand shake to C. A gave hand shake to C ( True or False)
2. If ” degg is boobo and tarra is kiki, is kiki boobo?
Then Comprehension, Word and Opposite /nearest in meaning,
My advice: You must be good in Maths, Logic and must be very very FAST, Its a tough test I must let you know, so Practice like MAD!!!!

DIAMOND BANK
Diamond test lasts for 1hr

It comprises 3 parts:
Part I
Simple Maths (1-10)
Chart/Graph Interpretation/Analysis (11-15)

Part II
English (1-10), e.g White:Black, Up: ?
Sentence completion/Appropriate fill in (11-15)

Part III
Critical/Logic Reasoning (1-10)
Series/Sequence (11-15)

Time is defintely short. There’s no -ve marking, read the instructions carefully, SCORE HIGH (because I think there cut-off is high)
Be careful to listen to the interview tips, immediately after the test (Very Important)

ECOBANK
Ecobank test is really tough and challenging. You really need to prepare very well because it’s interpretation of graph throughout. It’s like CAMBRIDGE EXAM. Anyway, people still pass it and you just have to prepare very well. Nothing is difficult if one prepares very well.

EQUITORIAL TRUST BANK
They are SAT related questions,the maths is the most difficult and time wasting because they are logical reasonings: For the English we have Comprehension, Sentence Correction, Verbal Reasoning. You have 30mins for the English of 40 questions and 30mins for the Maths, 30 questions.

The test format is numerical reasoning, graphical interpretation,then verbal reasoning.
just go to www.shl.com

FCMB
Their test is purely shapes, series i.e. 2, 4, –, 10 you understand what I mean? And GMAT English. The limiting factor is time constraint, you need to be fast but do not guess as there is negative marking. You have to compare symbols and choose which is the opposite of the original from options given.
I think its called quantitative aptitude.
