Question

the price of a book is reduced by 10% in a discount sale. if its present price is RS 180, find the original price​

Answer 1

Answer:

Lets take the original price to be = x

Price after discount = 180

Discount = 10%

First we minus the discount from 100; so, 100-10=90

= × x = Original Price

= × x = 180

= × x = 180

= x = = 180

= x = Rs. 200

∴ The original price of the book is Rs. 200.

Answer 2

CP = 10/100x180 = 18 rupees; CP = Discount + Present price = 18+180 = 198 rupees. Thefore 198 rupees is the answer.
