If X percent of 2.5X are 3X, then X could be?

  1. 90.
  2. 120.
  3. 150.
  4. 170.
  5. 180.

Answer(s): B

Explanation:

X percent is X/100.
X percent of 2.5X is (X/100)(2.5X) = (X/100)(5X/2) = 3X divide both sides by X. (X/40) = 3 ---> X = 120.



Gina and Tina’s average grade is 23 points higher than Tina’s grade. What is the difference between their grades?

  1. 23.
  2. 46.
  3. 16.
  4. 11.5.
  5. 15.

Answer(s): B

Explanation:

Define T as Tina’s grade and G as Gina’s grade.
Write the equation, T + 23 = (G + T)/2 2T + 46 = G + T T + 46 = G G – T = 46.



If Z is a positive integer and (192)5 is a multiple of 8Z, what is the largest possible value of Z?

  1. 5.
  2. 7.
  3. 8.
  4. 10.
  5. 12.

Answer(s): D

Explanation:

Factorize (192)5 and see what can be the largest value of Z. 192 = 64 x 3 = 8 x 8 x 3 ---> (192)5 = (8 x 8 x 3)5 = 35 x 810.
The largest possible value of 8Z which is a factor of (192)5 is the largest possible value of Z of which 8Z is a factor of 810. Z = 10.



Which of the following is the greatest possible common divisor of two different positive integers, both smaller than 124?

  1. 123.
  2. 122.
  3. 63.
  4. 62.
  5. 61.

Answer(s): E

Explanation:

A divisor is actually a factor of a number. Check each of the answers individually:
124 is divisor of itself, but obviously he has no other divisors smaller than 124. 63 is a divisor of itself and 126, which is bigger than 124.
62 is on the limit, we were asked for divisors less than 124. This is the right answer. 61 is a divisor of 61 and 122.



How many of the positive divisors of 120 are also multiples of 4 not including 120?

  1. 3.
  2. 4.
  3. 5.
  4. 7.
  5. 8.

Answer(s): D

Explanation:

Write down all the factors of 120: 60, 40, 30, 24, 20, 15, 12, 10, 8, 6, 5, 4, 3, 2, and 1.
Among these numbers only the following are multiples of 4: 4, 8, 12, 20, 24, 40 and 60.
