By selling 36 bananas, a vendor suffer a loss equal to the selling price of 4 bananas. Find his loss percent

Given :

By selling 36 bananas, a vendor suffers a loss equal to the selling price of 4 bananas.

To do :

We have to find the loss percent.

Solution :

Let the selling price of 1 banana be $Rs.\ 1$.

This implies,

The selling price of 36 bananas $= Rs.\ 36 \times1=Rs.\ 36$

Selling price of 4 bananas $= Rs.\ 4 \times 1= Rs.\ 4$

This implies,

Loss $=Rs.\ 4$

Cost price of 36 bananas $=$ Selling price of 36 bananas $+$ Loss

$= Rs.\ ( 36+ 4)$

$= Rs.\ 40$

Therefore,

Loss percent $= \frac{Loss}{Cost\ price}\times100 \%$

$= \frac{4}{40}\times100 \%$

$= 10 \%$

The loss percent is $10 \%$.
