Fresh fruit contains 68 % water and dry fruit contains 20 % water. How much dry fruit can be obtained from 100 kg of fresh fruits?

Correct answer: B. 40 kg

  • A. 32 kg
  • B. 40 kg
  • C. 52 kg
  • D. 80 kg

Explanation

The 100 kg fresh fruit contains 100 kg × 32% = 32 kg of dry matter because its water content is 68%. Dry fruit is 80% dry matter, so its mass is 32 kg ÷ 0.80 = 40 kg. A student may choose a, 32 kg, by forgetting that the obtained dry fruit still contains 20% water.
