Top 15 Aptitude Test Questions and Answers

Aptitude tests can be a valuable tool for measuring your natural abilities and potential. If you are considering applying for a job or program that requires an aptitude test, it is a good idea to start preparing early.

Practice these 15 most frequently asked aptitude questions with answers, and identify your strengths and weaknesses.

Basic Mathematics Aptitude Questions

Question 1: If the price of a shirt is increased by 20%, by how much percent should its consumption be reduced so that the expenditure remains the same?

a) 16.67%

b) 14.32%

c) 16.50%

d) 12.84%

Solution: Let the original price of the shirt be x; New price = 1.2x

Let the original consumption be y.

New consumption = y – (y * k/100), where k is the reduction percentage.

According to the problem, the expenditure remains the same.

Original expenditure = New expenditure

xy = (1.2x) * (y – (y * k/100))

Simplifying the equation,

100y = 120(y – (y * k/100))

100y = 120y – 120yk/100

120yk/100 = 20y

k = (20 * 100) / 120

k = 16.67%

Therefore, correct option is Option A.

Question 2: The ratio of boys to girls in a class is 3:5. If there are 36 girls, how many boys are there in the class?

a) 20

b) 15

c) 22

d) 27

Solution:

Let the number of boys be 3x. Number of girls = 5x

According to the problem, 5x = 36.

x = 36 / 5

x = 7.2

Number of boys = 3 * 7.2 = 21.6 (approximated to the nearest whole number)

There are approximately 22 boys in the class.

Therefore, the correct answer is Option C.

Question 3: A shopkeeper sells an article at a profit of 20%. If the cost price is Rs.250, what is the selling price?

a) 500

b) 300

c) 50

d) 450

Solution:

Profit percentage = 20%

Cost price = Rs.250

Selling price = Cost price + Profit

Selling price = Rs.250 + (Rs.250 * 20/100)

Selling price = Rs.250 + Rs.50

Selling price = Rs.300

Therefore, the correct answer is Option B.

Question 4: A bag contains 4 red balls and 6 blue balls. Two balls are drawn at random. What is the probability that both balls are red?

a) ⅓

b) ⅘

c) 2/15

d) 6/21

Solution:

Total number of balls = 4 (red) + 6 (blue) = 10

The probability of drawing the first red ball = 4/10

After one red ball is drawn, the number of red balls becomes 3 and the total number of balls becomes 9.

The probability of drawing the second red ball = 3/9

The probability of drawing both balls red = (4/10) * (3/9) = 2/15

Therefore, the correct answer is Option C.

Question 5: If 12 workers can build a wall in 9 days, how many days will it take for 8 workers to build the same wall?

a) 12 days

b) 10 days

c) 8 days

d) 13.5 days

Solution: Let the required number of days be x.

More workers take less time to complete the same work, so there is an inverse relationship between the number of workers and the number of days.

12 workers × 9 days = 8 workers × x days

12 × 9 = 8x

x = (12 × 9) / 8

x = 13.5

Therefore, the correct answer is Option D.
