For 60 people, the provision last for 18 days.
When the number of people increases, the provision decreases, that is, number of days decreases. [inversely related]
Total provision = 60*18
Now, the new strength = 72
Days the provision last = x
60*18 = 72*x
x= 15 days.
So, for 72 people, the provision will last for 15 days.
Hope it helps.
