GMAT Sample Questions: Topic Wise GMAT Questions

Ratios and proportions form an important part of the GMAT quant section and you need to practice to perfect them. GMAT for non-math background students can be a bit challenging, but practice is the way to go. Here are a few questions to brush up your skills:

Question 1

The ratio of boys to girls in a class is 3:2. If there are 30 students in the class, how many girls are there?

Explanation

To solve this problem, we need to find the number of girls in the class given the ratio of boys to girls.

The ratio of boys to girls is 3:2, which means that for every 5 students, 3 are boys and 2 are girls.

Since there are 30 students in the class, we can divide 30 by 5 to find the number of groups of 5 students:

• 30 ÷ 5 = 6 groups

Each group has 2 girls, so the total number of girls in the class is:

• 6 groups × 2 girls per group = 12 girls

Therefore, there are 12 girls in the class.

Question 2

The ratio of the number of apples to the number of oranges in a basket is 5:3. If there are 40 pieces of fruit in the basket, how many oranges are there?

Explanation

To solve this problem, we need to find the number of oranges in the basket given the ratio of apples to oranges. 

The ratio of apples to oranges is 5:3, which means that for every 8 pieces of fruit, 5 are apples and 3 are oranges.

Since there are 40 pieces of fruit in the basket, we can divide 40 by 8 to find the number of groups of 8 pieces of fruit:

• 40 ÷ 8 = 5 groups

Each group has 3 oranges, so the total number of oranges in the basket is:

• 5 groups × 3 oranges per group = 15 oranges

Therefore, there are 15 oranges in the basket.

Question 3

The ratio of the number of boys to the number of girls in a school is 3:2. If the total number of students in the school is 750, how many boys are there in the school?

Explanation

To solve this problem, we need to find the number of boys in the school given the ratio of boys to girls.

The ratio of boys to girls is 3:2, which means that for every 5 students, 3 are boys and 2 are girls.

Since the total number of students in the school is 750, we can divide 750 by 5 to find the number of groups of 5 students:

• 750 ÷ 5 = 150 groups

Each group has 3 boys, so the total number of boys in the school is:

• 150 groups × 3 boys per group = 450 boys

Therefore, there are 450 boys in the school.

Question 4

The ratio of the number of pens to the number of pencils in a box is 2:3. If there are 25 writing instruments in the box, how many pens are there?

Explanation

To solve this problem, we need to find the number of pens in the box given the ratio of pens to pencils.

The ratio of pens to pencils is 2:3, which means that for every 5 writing instruments, 2 are pens and 3 are pencils. Since there are 25 writing instruments in the box, we can divide 25 by 5 to find the number of groups of 5 writing instruments:

• 25 ÷ 5 = 5 groups

Each group has 2 pens, so the total number of pens in the box is:

• 5 groups × 2 pens per group = 10 pens

Therefore, there are 10 pens in the box.

Question 5

The ratio of the number of red balls to the number of blue balls in a bag is 4:3. If there are 21 balls in the bag, how many blue balls are there?

Explanation

To solve this problem, we need to find the number of blue balls in the bag given the ratio of red balls to blue balls. The ratio of red balls to blue balls is 4:3, which means that for every 7 balls, 4 are red and 3 are blue. Since there are 21 balls in the bag, we can divide 21 by 7 to find the number of groups of 7 balls:

• 21 ÷ 7 = 3 groups

Each group has 3 blue balls, so the total number of blue balls in the bag is:

• 3 groups × 3 blue balls per group = 9 blue balls

Therefore, there are 9 blue balls in the bag.
