So,  
x + 10x/100 = 7150 
(100x+10x)/100 = 7150 
110x/100 =7150 
11x/10 = 7150 
11x = 7150 × 10 
x = 71500/11 
   = 6500 
? Original cost of the furniture is Rs 6500 
 
8. A refrigerator is available for Rs. 13750 including VAT. If the rate of VAT is 
10%, find the original cost of the refrigerator. 
Solution: 
Given, 
Cost of refrigerator inclusive of VAT is = Rs 13750 
VAT = 10% 
Let us consider the original cost of refrigerator be = Rs x 
VAT at the rate of 10% on Rs x = Rs 10/100 × x = Rs 10x/100 
So,  
x + 10x/100 = 13750 
(100x+10x)/100 = 13750 
110x/100 = 13750 
11x/10 = 13750 
11x = 13750 × 10 
x = 137500/11 
   = 12500 
? Original cost of the refrigerator is Rs 12500 
 
9. A colour T.V. is available for Rs. 13440 inclusive of VAT. If the original cost of 
TV is Rs. 12000, find the rate of VAT. 
Solution: 
 
 
 
 
 
 
Given, 
Cost of TV inclusive of VAT is = Rs 13440 
Original cost of the TV is = Rs 12000 
So, let us consider the rate of VAT = x% 
VAT at the rate of x% on Rs 12000 = Rs x/100 × 12000 = Rs 120x 
So,  
12000 + 120x = 13440 
120x = 13440-12000 
120x = 1440 
x = 1440/120 
   = 12 
? Rate of VAT = 12% 
 
10. Reena goes to a shop to buy a radio, costing Rs. 2568. The rate of VAT is 7%. 
She tells the shopkeeper to reduce the price of the radio such that she has to pay Rs. 
2568, inclusive of VAT. Find the reduction needed in the price of radio. 
Solution: 
Given,  
Cost of the radio is = Rs 2568 
VAT = 7% 
Let the reduced price of the radio after discount be Rs x. 
Then, 
VAT = 7% of x = Rs 7x/100 
So, SP = Rs (x+7x/100) = Rs 107x/100 
It is given that the selling price should be Rs 2568 
107x/100 = 2568 
107x = 2568 × 100 
x = 256800/107 
   = 2400 
Reduced price of the radio after discount = Rs 2400 
? Reduction needed in the price of the radio is Rs (2568 - 2400) = Rs 168 
 
11. Rajat goes to a departmental store and buys the following articles: 
Item Price per item Rate of VAT 
2 Pairs of shoes 
1 sewing machine 
2 tea – sets 
Rs 800 
Rs 1500 
Rs 650 
5% 
6% 
4% 
 
Calculate the total amount he has to pay to the store. 
 
 
 
 
 
 
Solution: 
Given, 
CP of 2 pair of shoes = Rs 800×2 = Rs 1600 
Rate of VAT = 5% 
So, 
VAT = 5% of 1600 = 5/100 × 1600 = Rs 80  
So, amount Rajat paid for 2 pair of shoes = Rs (1600+80) = Rs 1680 
 
CP of 1 sewing machine = Rs 1500 
Rate of VAT = 6% 
So, 
VAT = 6% of 1500 = 6/100 × 1500 = Rs 90  
So, amount Rajat paid for 1 sewing machine = Rs (1500+90) = Rs 1590 
 
CP of 2 tea-sets = Rs.650 ×2 = Rs 1300 
Rate of VAT = 4 % 
VAT = 4% of 1300 = 4/100 × 1300 = Rs 52  
So, amount Rajat paid for 2 tea-sets = Rs (1300+52) = Rs 1352 
 
? Total amount Rajat needs to pay is Rs (1680+1590+1352) = Rs 4662 
 
12. Ajit buys a motorcycle for Rs. 17600 including value added tax. If the rate of 
VAT is 10%, what is the sale price of the motorcycle? 
Solution: 
Given,  
Cost of motorcycle including VAT = Rs 17600 
Rate of VAT = 10% 
Let us consider the sale price be = Rs x 
VAT at the rate of 10% on Rs x = Rs 10/100 × x = Rs 10x/100 
So,  
x + 10x/100 = 17600 
11x/10 = 17600 
11x = 17600×10 
x = 176000/11 
   = 16000 
? Sale price of the motorcycle is Rs 16000
