Question

a trader professes to sell his goods at a nominal gain percentage but actually earns 37 1 /2% profit by using false weight . lf for a kg he uses a weight of 800 gram what is the nominal gain % at which he claims to be selling his goods?

Answer 1

The trader professes to sell his goods at a loss of 8%.
Therefore, Selling Price = (100 - 8)% of Cost Price
or SP = 0.92CP

But, when he uses weights that measure only 900 grams while he claims to measure 1 kg.
Hence, CP of 900gms = 0.90 * Original CP

So, he is selling goods worth 0.90CP at 0.92CP
Therefore, he makes a profit of 0.02 CP on his cost of 0.9 CP

Profit % = 
i.e.,  or 2.22%
