Let’s say the market rate of that particular commodity is Rs 1 per gm.
Cheating 10% by using false weight at the time of buying means:
He bought 10% “extra” quantity. So, he had to pay Rs 100 for 100 gm but actually he got 110 gm for Rs 100.
CP of 110 gm = Rs 100
Cheating 10% by using false weight at the time of selling means:
He sold 10% “less” quantity. So, he sold saying that he was charging Rs 100 for 100 gm (at the market rate Rs 1 per gm) to his customer but gave only 90 gm.
SP of 90 gm = Rs 100 {Rate = (Rs 100/90 per gm)}
But he will sell all the quantity that he purchased i.e. 110 gm to calculate his profit.
SP of 110 gm = (100/90) x 110
SP of 110 gm = Rs 122.22
Profit % = [(SP - CP)/CP] x 100 = [(122.22 - 100)/100] x 100
Profit % = 22.22%
