Answer 1

Given:

Number of pens bought for 1 rupee = 15

Profit percentage = 50%

Formula:

New selling rate can be obtained by: Total units bought × (1 + (Profit% / 100))

Calculation:

Number of pens sold for 1 rupee = Total units bought/(1 + (Profit% / 100))

⇒ 15/(1 + (50 / 100))

⇒ 15/1.5 = 10

Therefore, he should sell 10 pens for a rupee to earn a profit of 50%.
