A garrison is provided with ration for 60 soldiers to last for 72 days. Find out how many days they will last if soldiers are 40 and they increase their intake by 20%?
1). 75
2). 90
3). 108
4). 135
It is a case of indirect proportion
More men, Less days
Number of days = (60 × 72)/(40 × 120/100) = 90 days
