Question

there are 1200 students in a hostel.food provision for them is for 25 days .how long will these provisions last if 300 more students join the group

Answer 1

Answer

1200 students = 25 days

If 300 more join (1200+300=1500) = ?

Using arrow method

Students Days

1200 ⬇️ 25 ⬆️

1500 ⬇️ x ⬆️

( More no.of students lesser the provision lasts)

Therefore, we'll use inverse method..

x/25=1200/1500

x=1200*25/1500

=4*25/5=4*5=20

Therefore the provision lasts for 20 days...
