Step-by-step explanation:
Let cost price of one book be ₹x
Thus cost price of 15 books will be 15x
Selling price of 12 books will be 15x
Selling price of one book is 15x/12 = 1.25x
We know Profit % = (selling price - cost price)/cost price ×100
Profit % = (1.25x - x)/x × 100
= 0.25x/x × 100
= 0.25 × 100
= 25%
