Question

A person buys $100$ cups at Rs. $20$ each. On the way $10$ cups are broken. He sells the remaining cups at Rs. $22$ each. His loss percent is :

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

The correct option is A $1$

$\Rightarrow$ Total cost price of 100 cups = $100\times Rs.20=Rs.2000$

$\Rightarrow$ Total number of cups after 10 cups broken = $100-10=90$

$\Rightarrow$ Selling price 90 cups = $90\times Rs.22=Rs.1980.$

$\Rightarrow$ Loss = $2000-1980=Rs.20$

$\Rightarrow$ $Loss\%=\frac{20}{2000}\times 100=1\%$
