Question

A dishonest dealer claims to sell goods at their Cost Price. He uses a weight of 900 gms in place of 1 kilogram. His real gain % is :

• A. 10%
• B. 11.11%
• C. 11%
• D. 12.22%

Answer 1

The correct option is B

11.11%

Let the cost of 1 kg (i.e 1000 g) = ₹ 100.

Since, he uses a weight of 900 gms in place of 1 kilogram,
Cost Price = ₹ 90
Selling Price = ₹ 100
$Gain\%=\frac{Gain}{CostPrice}$
$Gain\%=\frac{₹10}{₹90}\times 100=11.11\%$
