Answer 2

A bookseller purchased 100 story books for ₹ 2000

⇒ 100 books = ₹ 2000

⇒ 1 book = ₹ 2000/100

⇒ 1 book = ₹ 20/1

⇒ 1 book = ₹ 20         ..............(Cost Price)

And Sold each storybook for  ₹24

⇒ 1 book = ₹ 24         ..............(Selling Price)  

Profit = Selling Price - Cost Price

⇒ Profit = ₹ 24 - ₹ 20

⇒ Profit = ₹ 4        

Profit Percentage = Profit/Cost Price × 100 %

⇒ Profit Percentage = 4/20 × 100 %

⇒ Profit Percentage = 1/5 × 100 %

⇒ Profit Percentage = 100/5 %

⇒ Profit Percentage = 20 %
