Question

Cost price for $15$ items is $122.5$ and selling price of $12$ items is $108$. Then, the number of articles sold to make a profit of Rs. $75$ is:

• A. $66$
• B. $50$
• C. $44$
• D. $30$

Answer 1

Answer: (B)

$50$

Cost price of $15$ articles is $122.5$ Rs

So, cost price of one article $=\frac{112.50}{15}=\frac{22.5}{3}=$ Rs. $7.5$
Selling price of $12$ articles is Rs. $108$
So, selling price of one article $=$ Rs. $\frac{108}{12}=$ Rs. $9$
Profit on one article $=9-7.5=$ Rs. $1.5$
Number of articles sold to make a profit of Rs. $75=\frac{75}{1.5}=50$
