Question

A school hostel has enough food for 600 students for 30 days. If 120 students join the hostel. How long will the food last ?​

Answer 1

Answer

120 students = x days. Therefore the food will last for 160 days

Answer 2

600 students food consume=30 days

1 student food consume = 30/600

Students increase =120

Therefore (600+120)

720 students consume =30/600*720

Sice for 720 students the food lasts in 36 days
