A trader sold half of his articles at 60% profit, half of the remaining at 20% loss and the rest was sold at the cost price. In total transaction his gain % or loss % will be:

Gain 25%

Let the cost of cloth=100 Rs

then price of half cloth=50 Rs.
profit=60 %
Then S.P. of half cloth=$50\times \frac{\mathrm{160/}}{100}=80Rs.$
Price of one fourth cloth=40 Rs.
loss 20%
Then S.P of one fourth cloth=$25\times \frac{\mathrm{80/}}{100}=20Rs.$
The remaining 25 m cloth's S.P.= 40
$TotalS.P.=80+20+25=125Rs.$
$Profit=125-100=25Rs.$
$Profitpercentage=25\times \mathrm{100/100}$

The correct answer is Option (4) → Gain 25%
