A garrison has provision for 30 days for certain men. If 2/3 of them do not attend the mess then the food will last for?
- 90 days
- 50 days
- 60 days
- 65 days
Explanation
If 2/3 of the men do not attend the mess, that means only 1/3 of the men are attending the mess.
Since the provision is for 30 days for the entire group, the food will now last three times as long, since only one-third of the group is consuming it.
So, the food will last for 30 x 3 = 90 days.
