Answer 2

Answer:

answer is below

Step-by-step explanation:

Answer:

hey mate your answer is 4.167%.

Step-by-step explanation:

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 = 960x (because the goods he actually gives is 960g)

So,

Percentage Gain = [(1000x - 960x) * 100] / 960x

Percentage Gain = [(40x) * 100] / 960x

Percentage Gain = 4000x / 960x

Percentage Gain = 25/6x = 4.167%

Hence, his percentage gain is 4.167%
