Question

in a hostel there were provision for 300 students for 45 days after 31 days 195 student leave the hostel how long did the remaining provision last for reminding student

Answer 1

Let us take n as provision for one student for one day

provision for 300 students for 45days = 300*45*n = 13500n

food used by 300 students for 31days = 300*31*n = 9300n

Food left = 13500n - 9300n = 4200n

No of students after 31days = 300 - 195 = 105

food needs 105 sudents for one day = 105n

No of days the remaining provision will last = 4200n/105n = 40days
