Correct Answer – Option 1 : 3.5%
Given:
A / B = 90 / 100 = 9 / 10
B / C = 115 / 100 = 23 / 20
Concept:
Calculate the ratio of A, B and C. Then, using the ratio values, calculate the % difference.
Calculation:
A / B = 9 / 10
B / C = 23 / 20
⇒ A ∶ B ∶ C = 207 ∶ 230 ∶ 200
∴ A – C = 207 – 200 = 7
⇒ % difference between A and C with respect to C = (7 / 200) × 100 = 3.5%.
