A man sold two washing machines for79900 each. He sold one at a gain of 10% andthe other at a loss of 10%. Find his gain orloss % in the whole transaction.

Answer»

For 1st washing machine :

Cp = 9900

Profit %= 10%

Sp = 9900 + 9900 /100 * 10 ( taking out the percentage) = Rs 10,980 Profit = Rs 990

For 2nd washing machine:

Cp = 9900

Loss % = 10 %

Sp = 9900 - 9900/100*10 = Rs 8910

loss = Rs 990

Balance on whole transaction = 10980 - 8910 = 1980

Therefore his profit is = 1980And profit % = 1980 / 19800 (9900 * 2) * 100 = 10 %

answer is coming 1 percent loss
