Question

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

Answer 1

Answer:

The Cost Price of the Washing Machine is Rupees 16,875

Step-by-step explanation:

Given:

Selling Price of the Washing Machine (S.P) = 13,500

Loss made on selling the washing machine = 20 %

--------------------------------------------------------------------------------------------------------------

The percent she sold the washing machine was 100% - 20% = 80% of the Cost Price

Cost Price of the Washing Machine = 100/(100-loss%) × Selling Price

= 100 / 80 * 13,500

= 1350 * 10 / 8

= 1687.5 * 10

= Rupees 16,875

Therefore, the Cost Price of the Washing Machine is Rupees 16,875

Answer 2

SOLUTION:-

Given:

•Juhi sells a washing machine for Rs.13500.

•She losses 20% in the bargain.

To find:

The price at which she bought it.

Explanation:

• Selling price of Washing machine=Rs.13500
• Loss= 20%

Let the cost price of Washing machine be Rs.M

•Loss= Loss% of cost price

Loss= 20% of M

$loss = \frac{20}{100} \times M \\ \\ loss = \frac{1}{5} M$

We know that, Loss= C.P. - S.P.

Selling price = Cost price - loss

$= > 13500 = M - \frac{M}{5} \\ \\ 13500 = \frac{5M -M}{5} \\ \\ 13500 = \frac{4M}{5} \\ [Cross \: multiplication] \\ \\ 67500 = 4M \\ \\ M = Rs.\frac{67500}{4} \\ \\ M = Rs.16875$

Thus,

The cost price at which she bought Rs.16875.
