Given:

A 20% reduction in the price of an apple enables a man to buy 10 apples more for ₹54.

Formula used:

Let the original price of an apple be ₹x.

After a 20% reduction, the new price = x - 0.2x = 0.8x

Let the original number of apples be n.

Given: 54 = n × x and 54 = (n+10) × 0.8x

Calculations:

54 = n × x

⇒ n = 54/x

54 = (54/x + 10) × 0.8x

⇒ 54 = 43.2 + 8x

⇒ 54 - 43.2 = 8x

⇒ 10.8 = 8x

⇒ x = 1.35

Reduced price per apple = 0.8 × 1.35 = 1.08

Reduced price per dozen = 1.08 × 12 = 12.96

∴ The correct answer is option 2.
