GAT Quantitative Reasoning 3

Question 1

If 3x + 7 = 22, what is the value of 6x + 14?

Accepted Answer

44

Answer

From 3x + 7 = 22, we get 3x = 15. The expression 6x + 14 = 2(3x + 7) = 2 × 22 = 44.

Question 2

A store offers a 20% discount on a shirt priced at 150 SAR. After the discount, a 15% VAT is added. What is the final price?

Accepted Answer

138 SAR

Answer

After 20% discount: 150 × 0.80 = 120 SAR. After 15% VAT: 120 × 1.15 = 138 SAR.

Question 3

What is the next number in the sequence: 2, 6, 18, 54, ___?

Accepted Answer

162

Answer

Each number is multiplied by 3 to get the next: 2×3=6, 6×3=18, 18×3=54, 54×3=162.

Question 4

If the average of five numbers is 24, and four of the numbers are 18, 22, 26, and 30, what is the fifth number?

Accepted Answer

24

Answer

The sum of all five numbers = 24 × 5 = 120. The sum of the four known numbers = 18 + 22 + 26 + 30 = 96. The fifth number = 120 - 96 = 24.

Question 5

A car travels 240 km in 3 hours. If it increases its speed by 20 km/h, how long will it take to travel 360 km?

Accepted Answer

3.6 hours

Answer

Original speed = 240/3 = 80 km/h. New speed = 80 + 20 = 100 km/h. Time = 360/100 = 3.6 hours.
