Question

The price of a T.V. set inclusive of sales tax of 9% is Rs 13,407. Find its marked price. If sales tax is increased to 13%, how much more does the customer has to pay for the T.V.?

Answer 1

 Total price paid for T.V. = Rs 13,407

The rate of sales tax = 9%

Let sale price = Rs y

According to question

y + 9% of y = Rs 13407

`=> "y" + (9y)/100 = "Rs." 13407`

`=> (109"y")/100 = "Rs." 13407`

`=>  "y" = (13407 xx100)/109 = "Rs." 12300`

New rate of sales tax = 13%

New total price for T.V. = Rs.12,300+ 13% of Rs.12,300

`= "Rs." 12300 +13/100 xx12300`

`= "Rs." 12300 + "Rs." 1599`

= Rs. 13899

More money paid = Rs. 13,899 – Rs. 13,407 = Rs. 492
