Question

A school hostel has enough food for 800 students for 80 days.After 5 days 50 students left the hostel.How long will the food last?

Answer 1

food require for 800 students for 5 days=800*5
the amount of food left after 5 days= 800*80-800*5=800*75
the no.of students remaining after 5 days=800-50=750
hence,the remaining food will last for
[800*75]/750=80days

Answer 2

Answer:

80 days

Step-by-step explanation:

A school hostel has enough food for 800 students for 80 days.

Number of students = 800

After 5 days 50 students left the hostel.

Remaining students = 800-50 = 750

ATQ

$800 \times 75 = x \times 750$

$\frac{800 \times 75}{750} = x$

$80 = x$
