Sum

A shopkeeper sells an article for Rs. 21,384 including 10% sales tax. However, the actual rate of sales tax is 8%. Find the extra profit made by the dealer.

#### Solution

Price of the article inclusive of sales tax = Rs. 21,384
Let y be the list price of the article
Rate of sales tax charged by the shopkeeper = 10%
According to the given statement, we have
21384 = y + y × 10/100
⇒ "y"="y"/10=21384
⇒ (11"y")/10=21384
⇒ "y"=(21384xx10)/11
⇒ y = Rs. 19440
When the sales tax is 8%, the actual sale price
= 19440 + 19440 xx8/100
= Rs. 20,995.2
Extra profit = Sale price of the article charged by shopkeeper − Actual sale price
⇒ Extra profit = Rs. 21,384 - Rs. 20.995.2 = Rs. 388.80
