Question

Sam buys $10$ apples for Re.$1$. At what price should he sell a dozen apples if he wishes to make a profit of $25\%$?

• A. Rs. $1.5$
• B. Rs. $0.5$
• C. Rs. $1.2$
• D. Rs. $0.2$

Answer 1

Answer: (A)

Rs. $1.5$

The cost price of $1$ apple $={\left(\frac{1}{10}\right)}^{th}$ of a rupee or Rs. $0.10$.
As Sam wishes to make a profit of $25\%$, his selling price per apple will be $0.10+25\%$ of $0.10=$ Rs. $0.125$.
If the selling price of $1$ apple is Rs. $0.125$, then the selling price of a dozen apples $=12\times 0.125$ $=$ Rs. $1.5$
