I purchased a watch for ₹ 330 and sold it at a loss 20 %. Find selling price of the watch.

Given:

Cost of watch is Rs 330

Sold at loss of 20%

To do: Find the selling price of the watch

Solution:

Cost price = Rs.330

Loss in % = 20%

Loss in Rs=  Cost price$\times\frac{20}{10}$

Loss in Rs = $330\times \frac{20}{100} = 66$

Selling price = cost price $-$loss

                       =330$-$66 

                       = 264

Therefore, the selling price is Rs 264
