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
