A Correct answer
Explanation

Let CP be x. 1.05x + 72 = 1.13x. 0.08x = 72. x = 72 / 0.08 = 900.

AI explanation

The difference in gain percentages is 13% minus 5%, which equals an 8% difference. This 8% of the cost price equals the Rs 72 difference in the selling price. Therefore, the cost price is calculated as 72 divided by 0.08, which gives Rs 900.
