1.	A is 10% less than B and B is 15% more than C. Find, by what %, A is more or less than C?1. 3.5%2. 5.5%3. 4.5%4. 5%
Answer» 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%.

A is 10% less than B and B is 15% more than C. Find, by what %, A is more or less than C?1. 3.5%2. 5.5%3. 4.5%4. 5%

Answer» 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%.
