Question

There are 100 students in a hostel.Food
provision for them is for 30 days. How long
will the provision last if 25 students
left the hostel?​

Answer 1

Step-by-step explanation:

Total students = 100

food provision for them is 30 days

Total Food for 100 students = 100×30

=3000

25 students left the hostel

Remaining students = 100-25

= 75

Total food was 3000

then the food provision for 75 students lasts for =3000/75

= 40 days

Answer 2

Step-by-step explanation:

first (100students)(30 days)

Now there are 100 -25 students

So,(75 students)(xdays)=(100)(30)

xdays={(100 students)(30days)} \75 students

x days =40

hence total days = 40
