Question

In a camp, there is enough food storage for 300 persons for 42 days. How long this stock will last if 20 more persons join the camp?​

Answer 1

Step-by-step explanation:

No. Of persons = 300

If 20 members are added = 300 +20 = 320

Now, do direct proportion method.

300 = 42

320 =?

Do cross multiply,

300x = 13440

x = 13440 / 300

x = 1344/ 30

x = 44.8

So, x = 45 { approx}
