Answer 2

Answer:

• She bought it for rs 16875

Step-by-step explanation:

The selling price of washing machine is rs 13500

She loss 20% in the bargain.

Let, Cost Price = rs x

We know, Cost price =Selling Price  + Cost Price X 20%

                ⇒ x = 13500 + x . $\frac{20}{100}$      

                ⇒ x - $\frac{x}{5}$ = 13500

               ⇒ $\frac{4x}{5}$  = 13500

              ⇒ x =13500.$\frac{5}{4}$

             ⇒ x = 16875

So, She bought it for rs 16875
