Question

A book is bought for * 80 and sold at a gain of 30%. What is the selling price of the book ?​

Answer 1

Answer:

= 7.97 rupees. THIS IS THE ANSWER.

Cost price of book =Rs.80

Selling price of book =Rs.100

Since (SP)>(CP), so there is a gain

Gain =(SP)−(CP)

=Rs.(100−80)

=Rs.20

Gain %={(gain/CP)×100}

={20/80)×100}

={20/20)×25}

=25%

Answer 2

Answer:

Rupees:- 7.97

Step-by-step explanation:

Given; cost price = 80 rupees

            profit = 30 percentage

Selling price = profit percentage -  cost price

                   =   30/100  - 80

                    =     3/10 - 80

                     =   3-800/10

                     =    797/10

                     = 7.97 rupees.
