Answer 1

Answer:

The food will exhaust in 54 days if there are 400 students.

Step-by-step explanation:

Given that:

There is enough food to feed 360 students for 60 days.

To Find:

For how long will the food take them if there are 400 students?

Let us assume:

The food will exhaust in x days if there are 400 students.

Formula used:

S₁ × D₁= S₂ × D₂

Where,

S₁ = Number of students = 360

D₁ = Number of days = 60

S₂ = Number of students = 400

D₂ = Number of days = x

Finding the value of x:

⟶ 360 × 60 = 400 × x

⟶ 21600 = 40x

⟶ x = 21600/400

⟶ x = 54

Hence,

The food will exhaust in 54 days if there are 400 students.
