Correct Answer - Option 2 : 25%

Given:

Cost price of 9 apples = Rs. 36

Selling price of 11 apples = Rs. 55

Concept:

Gain: The amount gained by selling a product with more than its cost price.

Formula Used:

Profit = Selling price – Cost Price

Profit percentage = (Profit /Cost Price) × 100

Calculation:

As, Cost price of 9 apples = Rs. 36

⇒ Cost price of 1 apple = Rs. 36/9 = Rs.4      ----(1)

Also, selling price of 11 apples = Rs. 55

⇒ Selling price of 1 apple = Rs. 55/11 = Rs. 5      ----(2)

From equation (1) and (2), we conclude that

Selling price > Cost Price

⇒ Profit = S.P - C.P = 5 - 4 = 1

Profit % = (1/4) × 100 = 25%

∴ The profit percent is 25%.
