Ques. A girl buys a table fan that costs INR 1000 and sells the fan at a loss of 15%. Find out the selling price of that table fan.
Solution: Cost Price of the table fan is INR1000
percentage of loss is 15%
Loss percentage = (Loss/Cost Price) x 100
15 = (Loss/1000) x 100
So, Loss = INR 150
And,
Loss = Cost Price – Selling Price
Therefore, Selling Price = Cost Price – Loss
= 1000 – 150
Selling Price = INR 850
