The shopkeeper earned aprofit of 8%even after giving 5.5% discount on the printed price rs 12000 of a fridge.wahat was the cost of the fridge to the shopkeeper?
Answers
To solve these questions, you can form simultaneous equations:
First let price of t.v be x and that of the fridge be y
5% gain on chair= 5/100x= 0.05x
10%gain on fridge= 10/100y =0.1y
Therefore 0.05x + 0.1 y = 2000(total profit).....first equation(hence 5x+10y=200000)
10%gain on t.v = 10/100x =0.1x
5%loss on fridge= -5/100y =-0.05y
Therefore 0.1x - 0.05y = 1500......our second equation (hence, 5y= 10x-150000...y = (10x-150000)/5....y=2x-30000
solve by substitution: y= 2x-30000
5x+10y=200000
5x + 10(2x-30000)=200000
5x + 20x -300000= 200000
25x = 500000
x= 20000
y= 2x-30000
=2(20000)-30000 =40000-30000
=10000
Therefore the price of the tv = Rs. 20,000
price of the fridge= Rs. 10,000
