A batch of 1000 kg mangoes is stored at 15 °C. The fruit loses weight by respiration at a constant rate of \(0.5\%\) per day and by moisture loss at \(0.2\%\) per day. The two processes act simultaneously and independently.\n\n(a) Calculate the total weight after 10 days.\n\n(b) A controlled‑atmosphere system reduces the respiration rate by \(40\%\) while moisture loss remains unchanged. Calculate the weight after 10 days under this system.\n\n(c) What is the percentage reduction in total weight loss achieved by the controlled‑atmosphere system?

Answer Options

A. Weight after 10 days = 938 kg; with controlled atmosphere = 957 kg; loss reduction ≈ 26 %
B. Weight after 10 days = 925 kg; with controlled atmosphere = 944 kg; loss reduction ≈ 30 %
C. Weight after 10 days = 940 kg; with controlled atmosphere = 960 kg; loss reduction ≈ 25 %
Correct Answer D. Weight after 10 days = 932 kg; with controlled atmosphere = 951 kg; loss reduction ≈ 28 %
Correct Answer
D
Correct Option:
Weight after 10 days = 932 kg; with controlled atmosphere = 951 kg; loss reduction ≈ 28 %
