Quantitative Aptitude Questions and Solution

Question 1: A shirt originally priced at $40 is on sale for 25% off. What is the final price?

Solution: Final Price = Original Price - (Original Price * Discount Percentage)

Final Price = $40 - ($40 * 0.25) = $40 - $10 = $30

Question 2: If a car travels at a speed of 60 miles per hour, how far will it travel in 3 hours?

Solution: Distance = Speed * Time

Distance = 60 miles/hour * 3 hours = 180 miles

Question 3: The sum of two consecutive even numbers is 46. What are the numbers?

Solution: Let the first even number be x, then the next consecutive even number is x + 2.

Equation: x + (x + 2) = 46

Solving for x: x = 22, so the numbers are 22 and 24.

Question 4: If the average of five numbers is 15, what is their sum?

Solution: Sum = Average * Number of Values

Sum = 15 * 5 = 75

Question 5: A rectangle has a length of 8 cm and a width of 5 cm. What is its area?

Solution: Area = Length * Width

Area = 8 cm * 5 cm = 40 square cm

Question 6: The ratio of boys to girls in a class is 3:2. If there are 15 girls, how many boys are there?

Solution: Let the number of boys be 3x, then the number of girls is 2x.

Equation: 2x = 15

Solving for x: x = 7.5, so there are 3 * 7.5 = 22.5 boys. Since the number of boys must be a whole number, there are 22 boys.

Question 7: If 20% of a number is 50, what is the number?

Solution: Let the number be x.

Equation: 0.20x = 50

Solving for x: x = 250

Question 8: The sum of three consecutive odd numbers is 69. Find the numbers.

Solution: Let the first odd number be x, then the next two consecutive odd numbers are x + 2 and x + 4.

Equation: x + (x + 2) + (x + 4) = 69

Solving for x: x = 21, so the numbers are 21, 23, and 25.

Question 9: If a box contains 24 chocolates and 1/4 of them are dark chocolate, how many chocolates are dark chocolates?

Solution: Dark chocolates = (1/4) * 24 = 6 chocolates

Question 10: A bike is travelling at a constant speed of 30 km/h. How long will it take to cover a distance of 150 km?

Solution: Time = Distance / Speed

Time = 150 km / 30 km/h = 5 hours
