Question

The cost price of $18$ mangoes is equal to the selling price of $16$ mangoes. What is the profit percent?

Answer 1

Let the C.P of $1$ mango be $Rs.1$
Then C.P of $18$ mangoes will be $Rs.18.$
It is given that the
S.P of $16$ mangoes $=$ C.P of $18$ mangoes $=Rs.18$

C.P of $16$ mangoes $=Rs.16$

On selling $16$ mangoes, we can say that there is a profit.

Profit $=$ S.P of $16$ mangoes $-$ C.P of $16$ mangoes

$=18-16=Rs.2$

Profit $\%=\frac{Profit}{C.P}\times 100\%=\frac{2}{16}\times 100=12.5\%$
