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%.
