GRE Math Practice Questions: Designed To Make You A GRE Math Problems

Always evaluate your responses after each GRE Math practice to determine where you've gone wrong while answering specific questions. You'll comprehend the questions better by reading the GRE Math practice explanations below.

Question 1

The circle graph below shows the results of a survey taken of people who want a career working with animals.

Graph

If 400 people were surveyed, how many people chose to be animal trainers?

  • 36
  • 40
  • 45
  • 360
  • 364

Answer: 36

x = 400 × 9%

x = 400 × 0.09 = 400 × 9/100 = 36

Question 2

A survey on popular ice cream flavors in a school cafeteria is displayed in the bar graph.

Favorite Ice cream flavors

Which percent of students chose flavors in the top 2 categories?

  • 25%
  • 35%
  • 50%
  • 55%
  • 60%

Answer: 50%

The number of students who chose chocolate and chocolate chip was divided by the total number of students in the survey.

20 + 5 + 26 + 23 + 13 + 20 = 107

Top 2 flavors

26 + 23 = 49

49/107 ≈ 50%, slightly less than half the students chose chocolate or chocolate chip.

Question 3

In Canada, the cost of producing electricity accounted for 30% of all energy costs in a single year. How much was spent on the production of power if $30 billion was spent on energy?

Answer: 30% of the money spent on energy is given by 30% * 30 = 9.

Question 4

One pen costs $0.25, and one marker costs $0.35. What is the total cost of 18 pens and 100 markers at those prices?

Answer: $39.5

$0.25 * 18 = $4.5 + $0.35 * 100 = $39.5

Question 5

A jar containing 60 hard candies comes in 22 black, 18 blue, 11 orange, 5 maroon, and 4 violet hues. Consider that only one hard candy needs to be selected at random. The likelihood that the candy won't be either maroon or violet would then be what?

  • 0.09
  • 0.15
  • 0.54
  • 0.85
  • 0.91

Answer: 0.85

There are 4 violet candies and 5 maroons, 51 of which were neither violet nor maroon. The probability of selecting one of these is 51 out of 60. 51/60 = 0.85.

Question 6

What is the value of x if 8x+64 = 8-6x?

  • -4
  • -56
  • 12
  • 7
  • 4

Answer: -4

Thus, the following step is 8x+6x = -64+8. The subsequent step is, therefore, 14x = -56 and x = -4. Thus, the correct response is a) -4.

Question 7

When 3x2 + tx- 21 = (3x - 3)(x + 7) what is the value of t?

  • 18
  • -3
  • 21
  • 24
  • 18

Answer: 18

Use the method of FOIL (First, Outside, Inside, Last):

(3x - 3) (x + 7) = 3x2 +21x - 3x - 21 = 3x2 +18x -21 so t = 18

Question 8

The speed of light is 3.00 108 meters per second. How many kilometers per hour does the speed of light translate in scientific notation?

  • Quantity A is greater
  • The two quantities are equal
  • Quantity B is greater
  • The relationship cannot be determined

Answer: Quantity A is greater.

Rewrite quantity B so that it has the same base as quantity A. 49−3 can be rewritten as (72)−3, which is equivalent to 7−6. We can compare the two quantities. 7−5 is greater than 7−6.
