​

Answer 1

Answer:

Let initial quantity of food be x units

Assuming each student eats 1 unit of food per day, then we have = 15×30 = 450 units

In 4 days total food eaten = (15 student×1 unit per student×4 days) = 60 units

Remaining food = 450-60 = 390 units

After 4 days, remaining students = 13

Hence, remaining food will last =

390/(13 students × 1 unit of food) = 30 days
