Answer 2

Given:

Total number of students = 32

Time till which food lasts = 45

To find:

How much time the food will last if 16 students come

Solution:

Let the food consumed by students be = x

Therefore,

Total food = 32 × 45

Given that if there are 16 students who come, thus -

Total no.of students = 32+16

= 48

Solving -

x × 32 × 45 = 48

Solving -

x =  32 × 45 / 48

x = 16 × 45 /24

x = 720/24

x = 30

Answer: The food will last for 30 days if 16 more students come.
