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 per cent is

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

Answer 1

The correct option is B $1$

CP of a cup $=10$

Total CP $=100$

As $10$ cups are broken . Remaining are $90$ cups.

SP of each cup$=11$

Total SP $=99$

Loss =$100-99=1$

Loss % $=\frac{1}{100}\times 100=1$
