In a garrison there is enough food for 800 men for 20 days. After 5 days 200 men desert. How would the food will last now:

Explanation

Initially, there's enough food for 800 men for 20 days, meaning the total food available is 800 men x 20 days = 16,000 man-days of food.After 5 days, 800 men have consumed 800 men x 5 days = 4,000 man-days of food, leaving 12,000 man-days of food.With 200 men deserting, 600 men remain. The remaining food will now last for 12,000 man-days / 600 men = 20 days.Options A, C, and D are incorrect because the calculations show that the food lasts for 20 days after the changes. Option B is correct because it reflects this outcome accurately.
