An army camp of 200 men has enough food for 60 days. How long will the food last if the number of men in the camp is reduced to 160?

number of people in the army camp is 200. food which is fixed for them is 60 days

200 people reduced into 160

decrease in people=200-160

=40 persons

Let us find in percentage

40/200*100=20% decrease

population decrease leads to increase in food for less peoples.

so,20% of 60 days=20/100*60=12

peoples.

let’s add them in such a way that

60+12=72

hence food will last for 72 days if number of peoples reduced to 160.
