Given: Market Price =Rs.6,000, Rate of discount =30%
∴ The price of the article which the dealer paid to the wholesaler
=Rs.6,000−10% of 6,000
=Rs.6,000−30% of 6,000
=Rs.6,000−6,000×30100
=Rs(6,000−1,800)
=Rs.4,200
Sales tax paid by the dealer to the wholesaler
=6% of 4,200
=6×4,200100=Rs.252
Now for shopkeeper rate of discount =10%
∴ The price of the article which the shopkeeper paid to the dealer
=Rs.6,000−10% of 6,000
=Rs.6,000−Rs6,000×10100
=Rs.6,000−Rs.600
=Rs.5,400
The price paid by the shopkeeper including the tax
=Rs.5,400+6% of 5,400
=Rs.5,400+6×5,400100
=Rs.5,400+Rs.324
=Rs.5,724.
