Question

If a b and c positive variables and a+b+c=12,find the maximum value of a,b and c

Answer 1

Given :

a+b+c=12

The maximum value of a,b,c can be 10

So that:10+1+1=12

or: 1+10+1=12

1+1+10=12

All the other values then have to be minimum and 1.

You cannot write zero as any value as it is neither positive nor negative.

It is like the neutrons that is neutral.

Anyways we get the maximum value as 10

Hope it helps
