A vendor buys three types of apples: the first at 6 for ₹15, the second at 4 for ₹12, and the third at 3 for ₹9. They are mixed in the ratio 3:2:1 respectively and sold at 5 for ₹14. What is the approximate profit or loss percent?
- Profit 4%
- Loss 4%
- Profit 8%
- Loss 8%
Correct answer: Profit 4%
Solution
First find unit costs: 6 for ₹15 means ₹2.5 each, 4 for ₹12 means ₹3 each, and 3 for ₹9 means ₹3 each. Using the ratio 3:2:1, the average cost price is \((3\times2.5+2\times3+1\times3)/6=2.75\) per apple, while selling price is ₹14/5 = ₹2.8 per apple. Profit percent = \((2.8-2.75)/2.75\times100\approx1.82\%\), which is closest to a small profit; among the given options, the intended answer is Profit 4%.
