Answer» Correct Answer - Option 1 : 3.8%

Given:

A = 148%B

C = 160% of 2(A – B)

Calculation:

According to question

⇒ A = 148/100 × B

⇒ A = 1.48B      ----(1)

⇒ C = 160/100 × 2(A – B)

⇒ C = 3.2(A – B)

⇒ C = 3.2A – 3.2A/1.48

⇒ C = (4.736A – 3.2A)/1.48

⇒ C = 1.536A/1.48

⇒ C = 1.038A

⇒ C/A = 1.038/1

% of C more than A = (1.038 – 1)/1 × 100

⇒ 3.8%

∴ C more than A by 3.8%
