Show answer & explanation
Correct answer: C
Key idea: compute total cow-days and divide by the number of bags.
Total cow-days = number of cows × number of days = 40 × 40 = 1600 cow-days.
These 1600 cow-days are used to eat 40 bags, so cow-days per bag = 1600 ÷ 40 = 40 cow-days per bag.
Therefore one cow needs 40 days to eat one bag.
Answer: 40 days.
