Question

on selling an article for rs 144 a man loses 10% . at what price should he sell it to gain 20%

Answer 1

Selling price = 144

cost price = x

loss = 10%

loss %  = cp- sp  x 100

                  cp

10  =   x - 144   x 100

             x

10x  = 100x - 14400

100x - 10x  = 14400

90 x   = 14400

x   = 14400 / 90

cost price = 160

profit  = 20 %

profit  = 160 x (20/100)

          =  32

selling price = 160 + 32

                     =  rs. 192

so they have to sell at Rs. 192

Answer 2

Answer:

192

Step-by-step explanation:

selling price=144

let us take cost price=x

loss%= x-144/x * 100

10x=100x-144000

90x=14400/90

x= 160

profit (given) =20%

profit= 160*20/100

=32

selling price = 160+32

=192
