A is 48% more than B. C is 60% more than twice the difference between A and B. By what percent is C more than A (correct to one decimal place)?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e. 3.8%.

Let B = 100 and A = 148

Difference between A and B = 148 - 100 = 48

Twice the difference = 2 × 48 = 96

C = 96 × (8/5) = 153.6

C is more than A by = 153.6 - 148 = 5.6

Percentage increase = (5.6/148) × 100 ≈ 3.8%
