Question

A dishonest dealer professes to sell his goods at 10% profit on Cost Price and also uses a false weight and gives 900 grams instead of 1 kg. Find his net gain% .

Answer 1

Let Cost price be Rs.$C$/Kg

According to question , Sale Price = $C\times \frac{11}{10}$ $\times \frac{10}{9}$

So his net gain % = $\frac{200}{9}$%
