Let each man eat 1 unit of food per day.
Initial quantity of food = 800x62 = 49600 units
Quantity of food used in 56 days = 800x56 = 44800 units
Remaining amount of food = 49600-44800 = 4800 units
Remaining men = 800-560 = 240
So number of days the food will last = 4800/240 = 20 days
Question : There are 1200 men in a group. They have food for 80 days. After 5 days, 400 men left the group. The remaining food will last for how many days?
Option 1: 125 days
Option 2: 110.5 days
Option 3: 140.8 days
Option 4: 112.5 days
Question : There are 300 men in a group. They have food for 30 days. After 10 days, 100 more men join the group. The remaining food will last for how many days?
Option 1: 20
