1. 21/10, 11/21
2. 31/10, 12/21
3. 12/10, 13/21
4. 11/10, 21/11
5. 11/10, 11/21

Answer 1

Correct Answer - Option 1 : 21/10, 11/21

Given:

A = 10% more than C

Calculation:

Let C be 10

⇒ A = 10 × (110/100) = 11

⇒ (C + A)/C = (10 + 11)/10 = 21/10

⇒ (A/A + C) = 11/ (10 + 11) = 11/21

∴ The respective values are 21/10 and 11/21
