A refrigerator and a camera were sold for ₹12,000 each. The refrigerator was sold at a loss of 20% of the cost and the camera at a gain of 20% of the cost. The entire transaction results in which one of the following?

Answer»

No loss or gain
Loss of ₹ 1000
Gain of ₹ 1000
Loss of ₹ 2000

Solution :`x +y + (xy)/(100) = + 20 -20 - (20 xx 20)/(100)= - 4%`
Total sellingpriceof a refrigerator and a camera `= 12000 + 12000 = ₹ 24000`
Now , loss IS4%.
`CP xx (96)/(100) = 24000`
CP = ₹ 25000
Loss amount= (25000- 24000) = ₹10000
Alternate Mehod:
Whenitems aresold at same PRICEAND PRECENTAGE ofprofit & loss is same, thenloss occuured is always-
`(("common loss or gain")/(10))`
`= ((20)/(10))^(2) = 4% loss`
`=1000 ₹ ("for" 25000)`
