Answer 2

Let the provision day to be last now and the students at beginning 200 in the hostel mess.

It has a provision day of 30 and now there need to add 100 students.

But 100 students join so that decreases of provision occur.

It is to increase variations by calculating 200x30=6000/100=60.

Overall 60 days provision should be carried out in hostel.
