Correct Answer - Option 4 : 75%

**Given:**

A = 60% more than B

C = 66.67% of (A – B)

**Concept used:**

66.67% can also be written as 2/3

**Calculation:**

Let B be 100x

Then, A = 100x × (160/100) = 160x

And, C = (2/3) × (160x – 100x)

⇒ C = (2/3) × 60x = 40x

C is less than A by = (160x – 40x) = 120x

⇒ Required less % = (120x/160x) × 100% = 75%

**∴ ****C is 75% less than A**
