Given: Printed price of washing machine = Rs. 18,000, Rate of discount =20%.
Amount of discount to shopkeeper =20100×18,000
= Rs. 3,600
Shopkeeper's price = Rs. 18,000− Rs. 3,600
= Rs. 14,400
Sales Tax paid by shopkeeper =8100×14,400= Rs. 1,152.
Discount for consumer =10100×18,000= Rs. 1,800
Price for consumer = Rs. 18,000− Rs. 1,800= Rs. 16,200
Tax charged by the shopkeeper =8100×16,200= Rs. 1,296.
Since, Tax paid by the shopkeeper = Rs. 1,152
∴ VAT paid by the shopkeeper = Tax charged − Tax paid
= Rs. 1,296− Rs. 1,152
= Rs. 144
