Question

a bookseller sold a book for RS70 at a gain of 40percent find the profit​

Answer 1

Answer:

let cost price = x

selling price = x+40% of x

               70= x + (40/100)*x

              70  = x +(40x/100)

                 70  = (100x + 40x)/100

                 70= 140x/100

                  x= (70*100)/140

                  x= 50

Profit = selling price- cost price

profit = 70 -50 =20
