Since the shopkeeper sells the article for Rs.7,500 and changes sales tax at the rate of 12%
∴ tax charged by the shopkeeper = 12% of Rs.7500
= 12/100 x 7500 = 900
VAT = Tax charge – tax paid ,
⇒ Rs.180 = Rs.900 – Taxpaid
Tax paid by the shopkeeper = Rs. 900 – Rs.180 = Rs. 720
If the shopkeeper buys the article for Rs. x,
Tax on it = 12% of Rs.x = Rs.720 ⇒ x = Rs.6,000
∴ The price (inclusive of tax) paid by the shopkeeper = Rs.6000 + Rs.720 = Rs.6720.
