Answer 2

Answer:

Rs 13

Step-by-step explanation:

Find the profit of the 36 books:

Profit = 30% of Rs 360

Profit = 0.3 x 360 = Rs 108

Find the selling price of the 36 books:

Selling Price = Cost Price + Profit

Selling Price = 360 + 108 = Rs 468

Find the selling price of 1 book:

36 books = Rs 468

1 book = 468 ÷ 36 = Rs 13

Answer: The selling price if a book is Rs 13
