Question

Suman sells a washing machine for rs. 13500. she losses 10% in the bargain .what was the price at which she bought it

Answer 1

let's take Cost price as 100
loss 10%
selling price = 100 - 10% of 100
= 100 - 10
= 90
if s. p is 90 then c. p is 100
if s. p is 13500 then c. p = (100/90)x 13500
by simplify we will get c. p is 15000
