Question

Jyotsana bought a product for Rs 3,155 including 4.5% sales tax. Find the price before tax was added.

Sum

Solution

A product bought by Jyotsana for Rs. 3155 including 4.5% sales tax.

Let the price of the product before sales tax be Rs. x.

So, `x + x xx 4.5/100 = 3155`

⇒ `x + (x xx 45)/1000 = 3155`

⇒ `(1045x)/1000 = 3155`  ...[∵ Sales tax included in selling price]

⇒ `x = (3155 xx 1000)/1045`

= `3155000/1045`

= Rs. 3019.1387

⇒ x = Rs. 3019.14

Hence, the price of the product before sales tax is Rs. 3019.14
