Question

at a ca.mp there is sufficient food to last for 15 students for 30 days. after 4 days,2 students left the camp .how much longer will the food for

​

Answer 1

Answer:

Let the initial quality of food=x

Assuming each student eats 1 unit food daily,

15*30=450 units

In 4 days total food eaten=(15 students*1 unit per student*4 days)=60

Remaining food=450-60=390 units

After 4 days students=15-2=13

Hence, reaming food will last for,

390

13 student*1 unit

=30 days
