Answer options

  1. 250 days
  2. 230 days
  3. 200 days
  4. 170 days

Correct answer and explanation

Correct answer: 200 days

Explanation: āœ… Correct Answer: C. 200 days šŸ“š Explanation: Total food units = 4000 men x 190 days. Food used in 30 days = 4000 x 30. Remaining food = 4000 x (190 - 30) = 4000 x 160. After 800 men left, the remaining men are 3200. The number of days the food will last is (4000 x 160) / 3200. This calculation simplifies to (5 x 160) / 4, which equals 200 days.
