Q1. The list price of a refrigerator is ₹14650. If 6% is charged as sales tax, find the cost of the refrigerator.

Solution: we know that the list price =₹14650

Sales tax = 6%

So, Sales tax amount = 6% of ₹14650

= 6% × ₹14650

= ₹879

∴ Final price of the refrigerator = list price + sales tax

= 14650 + 879

= ₹15529

Q2. Reena bought the following articles from a general store:
i. 1 tie costing ₹250 with ST @ 6%
ii. Medicines costing ₹625 with ST @ 4%
iii. Cosmetics costing ₹430 with ST @ 10%
iv. Clothes costing ₹1175 with ST @ 8%
calculate the total amount to be paid by Reena

Solution: we know that the cost of a tie = ₹250, ST on tie = 6%

ST amount on tie = 6% of ₹250

= ₹15

∴ Final cost of tie = 250 + 15 = ₹265

We know that the cost of medicines = ₹625, ST on medicines = 4%

ST amount on medicines = 4% of ₹625

= ₹25

∴ Final cost of medicines = 625 + 25 = ₹650

We know that the cost of cosmetics = ₹430, ST on medicines = 10%

ST amount on cosmetics = 10% of ₹430

= ₹43

∴ Final cost of cosmetics = 430 + 43 = ₹473

We know that the cost of clothes = ₹1175, ST on medicines = 8%

ST amount on clothes = 8% of ₹1175

= ₹94

∴ Final cost of clothes = 1175 + 94 = ₹1269

So, the total amount to be paid by reena is ₹265 + ₹650 + ₹473 + ₹1269 = ₹2657

Q3. Tanvy bought a watch for 1980 including VAT at 10%. Find the original price of the watch.

Solution: we know that the VAT = 10%

SP = ₹1980

So let’s consider the original price of watch as x

∴ VAT amount = 10% of x

= x/10

∴ x + x/10 = 1980

(10x + x)/10 = 1980

11x /10 = 1980

x = (1980 × 10) / 11

x = 1800

∴ the original price of the watch excluding VAT is ₹1800

Q4. Mohit bought a shirt for 1337.50 including VAT at 7%. Find the original price of the shirt.

Solution: we know that the VAT = 7%

SP = ₹1337.50

So let’s consider the original price of shirt as x

∴ VAT amount = 7% of x

= 7x/100

∴ x + 7x/100 = 1337.50

(100x + 7x)/100 = 1337.50

107x /100 = 1337.50

x = (1337.50 × 100) / 107

x = 1250

∴ the original price of the shirt excluding VAT is ₹1250

Q5. Karuna bought 10 g of gold for 15756 including VAT at 1%. What is the rate of gold per 10 g?

Solution: we know that the VAT = 1%

SP = ₹15756

So let’s consider the original price of shirt as x

∴ VAT amount = 1% of x

= 1x/100

∴ x + x/100 = 15756

(100x + x)/100 = 15756

101x /100 = 15756

x = (15756 × 100) / 101

x = 15600

∴ the original price of the 10g Gold excluding VAT is ₹15600
