Total number of students = (75+15)
= 90 students
Number of days left = (30-6) days
= 24 days
For 75 students the remaining food would be continued for 24 days
For 1 student the remaining food would be continued for (24*75) days
For 90 students the remaining food would be continued for (24*75/90) days
= (24*5/6) days
= (4*5) days
= 20 days
(Ans): 20 days.
