Answer 2

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.
