## Profit/Loss Involving Sales Tax Problems Practice Worksheet

Example 1.
A retailer buys an article at a discount of 20% on the listed price from a wholesaler. The shopkeeper marks up the price by 10% on the listed price. A buyer pays Rs 220 to get it after paying a sales tax at the rate of 6 percent on the price asked for find the profit percentage.
Solution:
Let listed price be x Rebate on listed price = 20% of listed price.
Rebated price = x -20% of x
= x – 20x/100 = 80x/100
Effective marked price = listed price + 10% of listed price
= x + 10/100 × x
110x/100
Sales tax = 5% of the effective marked price = 5/100 × Rs 110x/100
= 55x/1000
Total cost = 110x/100 + 55x/1000
But total cost = Rs 220
1155x/100 = 220
Listed price = 19.04
Cost price for shopkeeper = 90x/100
90/100 x 19.04
= 17.136
Effective marked price = 110x/100
= 110/100 × 19.04
= 20.94
His profit = effective marked price – rebated cost price.
Rs(20.94 – 17.13)
= 3.81
His profit percentage = 3.81/17.13 × 100 = 22.24

Example 2.
A shopkeeper buys a carpet for Rs 2100 and marks up its price. A customer buys the carpet for Rs 3000 which includes a sales tax of 6% on the marked-up price. Find the markup percentage on the price of the carpet. Also, find his profit percentage.
Solution:
Let the marked-up price be x.
Cost of the carpet = Rs(2100 + x)
Sales tax = 10% of the marked up price
= 10/100 ×(2100 + x) = 2100+x/10
Total cost = Rs(2100 + x) + 2100 + x/10
21000 + 10x + 2100 + x/10
23100 + 11x/10
But total cost = Rs 3000
23100 + 11x /10 = Rs 3000
23100 + 11x = 30000
11x = 30000 – 23100
x = 33900
Increase in price = 33900
Percentage increase in markup price = 33.900/2100 × 100 = 1614.2
Hence percentage increase in markup price = 1614.2
His profit = increased price – cost price
3000 – 2100 = 900
Hence his profit percentage = 900/2100 × 100 = 42.85

Example 3.
A shopkeeper sells a balloon for Rs 30 including 3% sales tax however the actual rate of sales tax is 2%. Find the extra profit made by the dealer.
Solution:
Price of the balloon inclusive of sales tax = 30.
Let Y be the list price of the balloon.
Rate of sales tax charged by the shopkeeper = 3%
According to the given data
Y + (Y × 3/100) = 30
203Y/100 = 30
2.03Y = 30
Y = 30/2.03 = 14.77
When sales tax is 2% the actual sale price is 14.77 + 14.77 × 2/100
= 15.06
Extra profit = sales price of the article charged by a shopkeeper – actual sale price
Extra profit = 30 – 15.06 = 14.94

Example 4.
Raju Paid 384 sales on a purchase of 398 to find the rate of sales tax.
Solution:
Given that
Sale price = 398
Sales tax paid = 384
Rate of sales tax = sales tax /sale price × 100
= 384/398 × 100
96.48%
Therefore the rate of sales tax = 96.48

Example 5.
The price of a dressing table inclusive of sales tax is 13000 if the sales tax is 5%. Find the basic cost price.
Solution:
Selling price of dressing table = 13000
Rate of sales tax = 5%
Cost price = selling price × 100/100+ rate of sales tax
= 13000×100/100 + 5
= 12380.95
Therefore the basic cost price = 12380.95

Example 6.
Rohit purchases a bracelet costing 530 the rate of sales tax is 4 %. Find the total amount paid by Rohit for the bracelet.
Solution:
Given that
Sale price of bracelet = 530
Rate of sales tax = 4%
Total amount paid by Rohit = 530 + 4% of 530
= 530 + 4/100 × 530
= 530 + 21.2
= 551.2
Therefore the total amount paid by Rohit for the bracelet = 551.2
