A garrison of 1500 men has provisions for 6 weeks. At the end of the first two weeks 450 men desert. How long after this will the food last?
The garrison of 1500 men have provisions for 6 weeks.
After 2 weeks, the 1500 men have provisions left for 4 weeks.
Now, 450 men desert the garrison.
Men left =1500-450= 1050.
So, the food will now last for (1500/1050)*4 weeks = 40/7 weeks or 5 weeks and 5 days.
Hope this is the answer.
