Answer 2

Answer:

10 notebooks = Rs 400

Cost of 1 notebook = 400÷10= Rs 40

He sells 8 books = Rs 400

He sells 8 books = Rs 400Cost of each book= 400÷8= Rs 50

If he sells 8 books for Rs 40 = 40×8= Rs 320

Profit = 400-320

= 80

$profit \: percent = \frac{profit}{cost \: price} \times 100 \\ profit = \frac{80}{400} \times 10 \\ = 20$

The profit percent will be 20%
