Question

A shopkeeper sells one-third of his goods at a profit of $10\%$, another one-third at a profit of $20\%$ and the rest at a loss of $6\%$. What is his overall profit percentage?

Answer 1

Let the shopkeeper buy 300 g for Rs 300

Now he sells 100 g for Rs 110, another 100 g for Rs 120 and the rest 100g for Rs 94

$\therefore$ Total amount he recevies = Rs110+ Rs 120+ Rs 94

= Rs 324

$\therefore$ the shopkeeper spends Rs 300 and gets back Rs 324.

$\therefore$ his profit % = $\frac{24}{300}\times 100$%= 8%
