Question

The selling price of 10 books is equal to the cost price of 12 books. Find the profit percent.

Answer 1

Answer:

Profit = 20%

Step-by-step explanation:

Let us assume the cost price of 1 book is ₹ x

Cost price of 10 books = ₹ 10x

Selling price of 10 books = ₹ 12x

Profit = SP - CP = 12 x - 10x = ₹ 2x

$profit = \frac{2x}{10x} \times 100 = 20$
