(i) the sales tax amount, the customer has to pay.
(ii) the final price he has to pay for the colour T.V.
Solution
Catalogue price of T.V.= Rs. 18,000
Selling price for the shopkeeper
Two discount = 20% and 10%
`=18,000xx(1-20/100)(1-10/100)`
`=10,000xx80/100xx90/100`
= 12,960
Rate of sales tax = 10%
Sales tax paid by customer = 10% of 12,960
`=10/100xx12,960`
The sales tax amount the customer has to pay is Rs. 1,296.
Final price paid by customer = Rs. 12,960 + Rs. 1,296
= Rs. 14,256
The final price he has to pay for the Rs. 14,256
