Answer 2

A shopkeeper uses a weight of 960 g instead of 1000 g. The percentage gain is 4.167 %

Solution:

Given that,

A shopkeeper uses a weight of 960 g instead of 1000 g

To find: Gain percentage

$Percentage\ gain = \frac{selling\ price - cost\ price}{cost\ price} \times 100$

Here, from given,

Cost price = 960 g ( because he uses this instead of 1000 g )

Selling price = 1000 g

Therefore,

$Percentage\ gain = \frac{1000 - 960}{960} \times 100\\\\Percentage\ gain = \frac{40}{960} \times 100\\\\Percentage\ gain = 4.167$

Thus percentage gain is 4.167 %
