A baker buys three types of flour: wheat, rye, and oats. Wheat flour costs 5 for ₹40, rye flour at 6 for ₹45, and oats flour at 4 for ₹36. He mixes them in the ratio 2:2:3. He sells all the mixed flour at 3 for ₹32. What is his approximate profit or loss percentage?

Question

Accepted Answer

1. Find unit costs: wheat $40/5=₹8$, rye $45/6=₹7.5$, oats $36/4=₹9$.

2. Take parts 2:2:3. Total cost $=2	imes8+2	imes7.5+3	imes9=₹58$. Total quantity $=7$. Cost per unit $=58/7$.

3. Selling price per unit $=32/3$.

4. Profit per unit $=\dfrac{32}{3}-\dfrac{58}{7}=\dfrac{50}{21}$. Profit % $=\dfrac{50/21}{58/7}=\dfrac{350}{1218}\approx0.2874\approx29\%$.

5. **Answer: Profit of 29%**.
