Question 57

Selling price of 9 articles is equal to the cost price of 15 articles. In this transaction, there is profit of $66\frac{2}{3}\%$

Answer 1

True
Selling price of 9 articles = Cost price of 15 articles
It means, 15 articles - 9 articles = 6 articles
Cost price of 6 articles is the profit on transaction.
$\therefore Profit\%=\frac{6}{9}\times 100=\frac{600}{9}=\frac{200}{3}=66\frac{2}{3}\%$
