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).

Options
a) 14.94 %
b) 15.11 %
c) 18.21 %
d) 11.11 %

Solution

As per question
SP = 1000 g
CP = 870 g
P% = \frac{SP-CP}{CP} \times 100%
P% = \frac{1000-870}{870} \times 100%
P% = \frac{130}{870} \times 100% = 14.94%

Ans: a) 14.94 %
