Question
In an army camp, there were provisions for 550 men for 28 days. But, 700 men attended the camp. How long did the provisions last?
Solution
Number of days the provisions will last for 550 men = 28 days
Number of days the provisions will last for 1 man = 28 × 550 = 15400 days (less men means more days)
Number of days the provisions will last for 700 men = `15400/700` = 22 days
The provision will last for 22 days.
