Juhi sells a washing machine for ₹13,500. She loses 20% in the bargain. What was the price at which she bought it?

Solution:

Let us assume the cost price of the washing machine = Rs. 100

Loss is given as 20% of cost price = Rs. 20

So, the selling price will be = Cost price - loss

= 100 - 20

= Rs. 80

Using the unitary method.

If the selling price is Rs. 80, the cost price = Rs.100

Thus, if the selling price is Rs.13,500

The cost price = (100/80) × 13500

= Rs.16,875
