Question

A vendor purchased bananas at Rs.40 per dozen and sold them at 10 for Rs.36. Find his gain.

Answer 1

Cost Price $\frac{40}{12}=3.33$ rupees/banana

Selling Price $\frac{36}{10}=3.6$ rupees/banana

Therefore,

It is $43.2$ for $12$ bananas

$Profit=SellingPrice-CostPrice$

$=43.2-40=3.2$

Therefore,

$Profit\%=\frac{3.2}{40}\times 100$

$=8\%profit$

Hence, this is the answer.
