More number of students lesser number of days.thus they are in inverse proportion
relation of inverse proportion is
x1y1 = x2y2
100×20=125× y2
16= y2
thus the food provision will last for 16days if 25 more students join the hostel.

No. of students >>>>>>> 100
Food provision >>>>> 20 days
No. of students >>>>> (100+25) = 125
Food provision >>>>>> x days
Indirect variation
Therefore,
x/20 = 100/125
125x = 20 × 100
=> x = 20 × 100 /125
=> x = 4 × 4
=> x = 16
ANSWER = 16 DAYS
