Question

A person buys $100$ cups at Rs. $10$ each. On the way $10$ cups are broken. He sells the remaining cups at Rs. $11$ each. His loss percent is:

• A. $\frac{1}{2}$
• B. $1$
• C. $1\frac{1}{2}$
• D. $2$

Answer 1

The correct option is B $1$

$C.P.$ of $100$ cups $=10\times 100=$ Rs. $1000$

$10$ cups are broken then remaining cups $=100-10=90$

$S.P.$ of $90$ cups $=90\times 11=$ Rs. $990$

$Loss$ =$C.P$ - $S.P.$

$\Rightarrow 1000-990=$ Rs. $10$

$Loss$ $\%$ $=\frac{loss}{C.P}\times 100$

$=\frac{10}{1000}\times 100=1$ $\%$
