A grocer professes to sell rice at the cost price, but uses a fake weight of 870 g for 1 kg. Find his profit percentage (correct to two decimal places).

Correct option is B

Given:

Cheating while selling =870g instead of 1kg

Formula Used:

Profit Percentage = $$\frac{Profit}{Cost\ Price} \times 100$$​​

Solution:

At the time of selling he does a cheating of 130g

Let price of 1g of items = Rs. 1

Cost price of items = Rs. 870

Selling price if items = Rs. 1000

Profit = 1000 -870 = Rs. 130

Profit percentage =$$\frac{130}{870} \times100 = 14.94$$​%​
