A shopkeeper mixes 4 liters of a milk solution containing 25% fat with 6 liters of another milk solution containing 40% fat. What is the fat percentage in the final mixture?

Show answer & explanation

Correct answer: C

Explanation

Fat in the 4 L solution = 25%
Fat in the 6 L solution = 40%
Fat in the first solution =4×25100=1 L= 4 \times \frac{25}{100} = 1 \text{ L}
Fat in the second solution =6×40100=2.4 L= 6 \times \frac{40}{100} = 2.4 \text{ L}
Total fat = 1 + 2.4 = 3.4 L
Total solution = 4 + 6 = 10 L
Fat percentage =(3.410)×100=0.34×100=34%= \left( \frac{3.4}{10} \right) \times 100= 0.34 \times 100= 34\%
