Answer 1

Answer:

Ma nahi janta ki answawr is correct

Sorry, the other answer is incorrect.

Percentage Gain = [(Selling Price - Cost Price) * 100] / Cost Price

Suppose the cost price of 1g is x.

Therefore,

Selling Price = 1000x (because he claims to be giving 1kg

weight)

Cost Price = 900x (because the goods he actually gives is 900g)

So,

Percentage Gain = [(1000x - 900x) * 100] / 900x

Percentage Gain = [(100x) * 100] / 900x

Percentage Gain = 10000x / 900x

Percentage Gain = 100/9 = 11.11%

Hence, his percentage gain is 11.11%
