the hostel of a college having 320 students has a stock of food for 80 days if 20 students leave the hostel after 20 days for how many more days will the food last?

  • math -

    x/y is equal to students/days.
    Therefore,320students/60 days is equal to 300 students / y days.
    It is indirect variation.
    320× 60= 300y
    you = 320/300×60 =64 days.
    Hence the food will last more 4 days
