Answer: First( 100 students)×(20days)= total food eaten.—(1)
Now there are 100+25 students.
So, (125 students)×(x days)= total food eaten.—(2)
From 1 and 2
(125 students)×(x days)= ( 100 students)×(20days)
x days = {( 100 students)×(20days)}/125 students
x days = (4×20)/5= 4×4= 16.
Hence total days = 16.
