a camp of 1000 soldiers has enough food for 180 days if 600 more soldiers join the camp after 20 days how long will the remaining food last

Answer»

First
camp has food of 180 days for 1000soldier
so how much day can camp food LAST if he had only ONE soldier=1000*180=180000days
now from question for 20 days 1000 soldier have their food=20*1000=20000
so REMAINING food=180000-20000=160000

then 600 more soldier join them now total soldiers are 1000+600=1600
so no of days remaining food last will be 160000/1600=100days Answer
