Question

juhi sells a washing machine for 13500 she loses 20% in the bargain.what was the price at which she bought it?

Answer 1

sp = 13500rs
loss % = 20%
CP = [100 / (100 – Loss%)] * SP
CP = [100/(100 - 20)]* 13500
CP = [100/80]*13500 = (5/4)*13500 = 67500/4 = 16875rs

Answer 2

Selling price =13500
loss%=20%
Cost price=(100/100-loss) x selling price
=(100/100-20) x 13500
=100/80 x 13500
= Rs 16875
