Question

$12$ bananas are brought for Rs $10$ and $10$ bananas are sold for Rs $12$. Find the gain % or loss%.

Answer 1

Cost price of 1 banana is $\frac{10}{12}$

Selling price of 1 banana is $\frac{12}{10}$

Hence, profit = $\frac{12}{10}-\frac{10}{12}$

$⟹\frac{44}{120}=\frac{11}{30}$

profit $\%=\frac{\frac{11}{30}}{\frac{10}{12}}=0.44$ or $44\%$
