Question

A shopkeeper sold an article for Rs 450 at a loss of 10% at what price should he sell it so as to gain 10%

Answer 1

450×100÷110
=500
so cp=500
500×10÷100
=50
so 500+50
=550

Answer 2

Answer:

selling price = rs. 450

loss %   = 10

let cp = x

loss % = cp-sp   x 100

                 cp

10      =   x - 450  x 100

                  x

10x   = 100x - 45000

100x - 10x  = 45000

90 x  = 45000

 x  = 45000 / 90

cost price = 500

sp = 450

profit %  = 10

profit = 500 x 10/100

        = 50

selling price  = 500 + 50

                      = Rs. 550

so, they sell at Rs550
