Question

By selling $8$ dozen pencils$,$ a shopkeeper gains the selling price of one dozen pencils$,$ Find his gain percent$.$

Answer 1

We have

Total number of selling pencil $=8dozen$

and

gain$=1dozen$

Hence,

$gain\%=\frac{gain}{totalpencil}\times 100$

$=\frac{1}{8}\times 100$

$=\frac{25}{2}\left[dividedbothby4\right]$

$=12\frac{1}{2}\%.$
