90 students have provisions for 20-4=16days
So,Next then students inceased=90+30=120
Let the no. of days 120 student will eat be x days
so, table will be like this
No. of student. 90. 120
No. of days. 16. x
So,More student,less food and less student,more food
therefore,both the qty. are in inversely prop.
so,we have,120×x=90×16
x=90×16/120=12days
Hence,120 student will have provision for 12 more days
