Question

If the cost price of 18 mangoes is the same as the selling price of 16 mangoes. Find the gain percent.

Answer 1

Let the cost price of each mango be Re.$1$. Then,
$C.P.$ of $16$ mangoes $=Rs.16$
$S.P.$ of 16 mangoes $=Rs.18$
$Gain=S.P-C.P=Rs.(18-16)=Rs.2$
Now $Gain\%=(\frac{Gain}{C.P}\times 100)$%=$(\frac{2}{16}\times 100)\%=12.5\%$
