# Amna purchased a toy for Rs 660 including sales tax. If the rate of sales tax is 10%, then the selling price of the toy is _________

**Solution: **

The sales tax is always calculated on the sales price of an article. Therefore,

Let Sales Price of the toy = x

Sales tax is calculated on the selling price. Since the rate of sales tax is 10%, the sales tax on the toy can be calculated as:

Sales tax = (10/100) × (x) = x/10

The purchase price of the toy = x + x/10 = 11x/10

Since purchase price of the toy = Rs. 660, it implies:

11x/10 = 660

x = (660/11)(10)

= (60)(10)

= Rs. 600

**✦ ****Try this: **Amna wanted to purchase a toy at a marked price of Rs 660 excluding sales tax. If the rate of sales tax is 10%, then the selling price of the toy is _________.

Sales Tax = 10% of 660

= (10/100) × (660)

= Rs. 66

Purchase Price of the toy = Sales Price + Sales Tax

= 660 + 66

= Rs. 726
