Correct Answer - Option 1 : 25%

Given:

Cost price of dog = Rs. 1200

Selling price = Rs. 1500

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:

Profit = 1500 - 1200 = Rs.300

Profit % = (300/1200) × 100 = 100/4 = 25%

∴ The profit percent is 25%.
