Question 1. Find the buying price of each of the following when 5% G.S.T. is added on the purchase of
(i) a towel of ₹ 50
(ii) 5 kg of flour at ₹ 15 per kg.
Answer:
(i) G.S.T. = 5%
Cost of towel = ₹ 50
Total S.T. = (50 × 5)/ 100
= ₹ 2.50
So the buying price = 50 + 2.50 = ₹ 52.50
(ii) C.P. of 5 kg of flour at the rate of ₹ 15 per kg = 15 × 5
= ₹ 75
Rate of S.T. = 5%
Total tax = (75 × 5)/100
= 375/100
= ₹ 3.75
So the total price of the flour = 75 + 3.75 = ₹ 8.75
Question 2. If 8% of VAT is included in the prices, find the original price of
(i) a TV bought for ₹ 13500
(ii) a shampoo bottle bought for ₹ 180.
Answer:
(i) Total price of TV including VAT = ₹ 13500
Rate of VAT = 8%
Original price of TV = (13500 × 100)/ (100 + 8)
= (13500 × 100)/ 108
= ₹ 12500
(ii) Total cost of shampoo bottle including VAT = ₹ 180
Rate of VAT = 8%
Original price of shampoo = (180 × 100)/ (100 + 8)
= (180 × 100)/ 108
= 500/3
= ₹ 166.67
Question 3. Utkarsh bought an AC for ₹ 34992 including a VAT of 8%. Find the price of AC before VAT was added.
Answer:
Cost of AC including VAT = ₹ 34992
Rate of VAT charged = 8%
We know that
Original price of AC = (34992 × 100)/ (100 + 8)
By further calculation
= (34992 × 100)/ 108
= ₹ 32400
Question 4 Gaurav bought a shirt for ₹1296 including VAT. If the original price of the shirt is ₹ 1200, find the rate of VAT.
Answer:
Cost of shirt including VAT = ₹ 1296
Original price of shirt = ₹ 1200
Amount of VAT = 1296 – 1200 = ₹ 96
Rate of VAT = (VAT × 100)/ C.P.
= (96 × 100)/ 1200
= 8 %
Question 5. Anjana buys a purse for ₹ 523.80 including 8% VAT. Find the new selling price of the purse if VAT increases to 10%.
Answer:
Total C.P. of purse including VAT = ₹ 523.80
Rate of VAT = 8%
Actual cost of the purse = (523.80 × 100)/ (100 + 8)
By further calculation
= (523.80 × 100)/ 108
= ₹ 485
New rate of VAT = 10%
Amount of VAT = 485 × 10/100
= 4850/100
= ₹ 48.50
So the total cost of the purse = 485 + 48.50 = ₹ 535.50
Question 6. A wall hanging is marked for ₹ 4800. The shopkeeper offers 10% discount on it. If VAT is received 8% from the customer, find the amount paid by the customer to purchase the wall hanging.
Answer:
Marked price of wall hanging = ₹ 4800
Discount offered = 10%
Net sale price = [4800 × (100 – 10)/ 100]
By further calculation
= (4800 × 90)/ 100
= ₹ 4320
Rate of VAT charged = 8%
So the sale price including VAT = [4320 × (100 + 8)/ 100]
= (4320 × 108)/ 100
= 466560/100
= ₹ 4665.60

Question 7. Amit goes to a shop to buy a washing machine. The marked price of the washing machine is ₹ 10900 excluding 9% VAT. Amit bargains with the shopkeeper and convinces him for ₹ 10900 including VAT as the final cost of the washing machine. Find the amount reduced by the shopkeeper.
Answer:
M.P. of washing machine = ₹ 10900
Rate of VAT = 9%
Consider ₹ x as the reduced price of machine
VAT at the rate of 9% = x × 9/100 = ₹ 9x/100
So the amount paid = x + 9x/100 = 109x/100
109x/100 = 10900
x = (10900 × 100)/ 109
x = 10000
Amount reduced by the shopkeeper = 10900 – 10000
= ₹ 900
Hence, the amount reduced by the shopkeeper is ₹ 900.
