Question

A man bought $200$ pencils for Rs. $60$. He found that $10$ $\%$ of them were broken and sold the rest at $36$ paise each. His profit per cent is.

• A. $10$ $\%$
• B. $8$ $\%$
• C. $6$ $\%$
• D. $20$ $\%$

Answer 1

Answer: (B)

$8$ $\%$

CP of $1$ pencil is $\frac{60}{200}=$ Rs. $0.30$

Number of pencils broken $=20$

So, $180$ pencils were sold at Rs. $0.36$.

SP $=0.36\times 180=$ Rs. $64.8$

Profit $=$ Rs. $4.80$

So, $P\%=\frac{4.80\times 100}{60}$ $=8\%$
