Given: Listed price of an article=Rs.1,500, Rate of VAT=12%
VAT on the article=12100×1500,=Rs.180
Let C.P. of this article be x, then
VAT=12100×x,=Rs.12x100
If the shopkeeper pays a VAT =Rs. 36
Then 180−12x100=36
18000−12x100=36
18000−12x=3600
∴12x=18000−3600=14,400
x=Rs.1,200
∴ The price at which the shopkeeper purchased the article inclusive of sales tax
= Rs. 1,200+12100×1,200
=1,200+144
= Rs. 1,344.
