A man sold two computers for Rs. 24,000 each. On one he gained 20% and on the other, he lost 20%. Find his gain
or loss percentage of his whole transaction.

Answered 

Sale price of first computer = Rs 24000

gain = 20%

So cost of first computer = 100/120 x 24000 = Rs 20,000

Sale price of second computer = Rs 24000

Loss 20%

So cost of second computer = 100/80 x 24000 = Rs 30,000

Total cost = Rs 50,000

Total sale value = Rs 48000

Loss = Rs 2000

Loss % = 2000/50000 x100= 4 % LOSS ANSWER
