Answer: 1 Mark
Given, Selling price = ₹ 13,500
Loss% = 20%
Let the cost price be x.
∴Loss = 20% of x
Selling price = Cost price - Loss
⇒13500 = x−20100×x
⇒13500 = x−15x
⇒13500 = 45x
⇒x = 16875
Therefore, she bought it for ₹ 16875.
So, cost price of the article = ₹ 16875
20% of the cost price
=20100×16875=₹3375
Net amount = 16875 + 3375 = ₹ 20250
So, in order to sell the washing machine at 20% profit, she needs to sell it at ₹ 20250.
