Question

By selling $35$ greeting cards, a shopkeeper loses an amount equal to the selling price of $5$ greeting cards. Find his loss percent.

Answer 1

Let, S.P of $1$ Greeting Card be $Rs.x$

S.P of $35$ greeting Cards $=$ $Rs.(35\times x)=Rs.35x$

Loss $=$ S.P of $5$ greeting cards $=$ $Rs.x\times 5=Rs.5x$

CP of 35 greeting cards $=$ S.P $+$ Loss $=Rs.(35x+5x)=Rs.40x$

$Loss\%=\frac{Loss}{CP}\times 100$

$=\frac{5x}{40x}\times 100$

$=\frac{25}{2}=12.5$.

Hence, Loss is $12\%$.
