1600 men have provisions for 28 days in the temple. If after 4 days, 400 men leave the temple, how long will the food last now?

One Answer on this Question

1. Suppose 1 person consumes 1 unit food daily.
   So, for 24 days, 1600 person will consume 1600×24 units.
   So total units of food available = 1600×24

   Now total number of person =1200

   So, total food will be consumed by 1200 person in (1600×24)/1200 = 32 days.
