  1. A dishonest dealer professes to sell his goods at cost price. But he uses a false weight of 900 g per 1 kg weight. Find his gain percent ?
    1. 111/9%
    2. 103/9%
    3. 11%
    4. 10%
Correct Option: A

Gain percentage = [Error/(True value - Error)] x 100 %
= [(100/(1000 - 100)] x 100 %
= (100/900) x 100 %
= 111/9%
