Question

Arun sells a washing machine for rupees $13,500. He loses 20 % in the bargain. What was the price at which he bought it?

Answer 1

Selling price of Washing Machine= 13500

loss%= 20%

We know that

Loss%= Loss*100/Cost Price

20=Loss*100/ C.P.

loss/C.P.=1/5

If loss=x then CP=5x

Hence SP=CP-Loss , 5x-x=4x

according to question 4x=13500

∴ x= 3375

Hence Cost price= 5x= 5*3375= 16875

Answer 2

Given:purchase(MRP)=13500
bargain(discount)=20%
To find:price in which he purchase.
solution:discount=MRP×discount rate
=13500×20/100
=135×20--------two zero cut
=2700
total price=MRP-discount
=13500-2700
=$10800
