Q-1 On sellinga T.V. at 5% gain and a fridge at 10% gain , a shopkeeper gains Rs 2000.

But if he sells the T.V. at 10% gain and the fridge at 5% loss . He gains Rs 1500 on the transaction .

Find the actual price of T.V and fridge.

let the actual price of TV and fridge be Rs. x and Rs. y respectively.

% gain on TV = 5%

therefore gain on Rs. x =

% gain on fridge = 10%

therefore gain on Rs. y =

total gain = Rs. 2000

if the gain on TV is 10% and loss on fridge is 5% loss .

total gain = Rs. 1500

(1) +2*(2)

substituting the value of x in (1):

20000+2y=40000

2y = 40000-20000

2y = 20000

y = 20000/2 = 10000

thus the actual price of TV is Rs. 20000 and the actual price of fridge is Rs. 10000.

hope this helps you.

cheers!!
