Question

Juhi sells a washing machine for $Rs13500$. She loses $20\%$ in the bargain. What was the price at which she bought it?

Answer 1

Find the cost price:

The price at which Juhi bought the washing machine is the cost price of the machine

loss percentage$=\left(\frac{\cos tprice-sellingprice}{\cos tprice}\right)\times 100$

Let Cost price$=x$

By substituting the known values we get

$\Rightarrow$ $20=\frac{x-13500}{x}\times 100$

$\Rightarrow$ $x=5\left(x-13500\right)$

$\Rightarrow$$4x=67500$

$\Rightarrow$ $x=16875$

Hence, Juhi bought the washing for $Rs16,875$.
