Question

Each child in the family has at least one brother, two sisters and two parents.

What is the fewest number of children their parents might have?

Answer 1

Ooo this is like a riddle. Let me attempt to answer:

Let's start with one of the brothers. That's 1 child. There has to be 1 more brother for each brother to have one other brothers. Then for that brother to have two sisters, they have to have two girls. This is 4 children.

Now from a girl's perspective. You are a girl so you are already 1 child. To have one brothers, there has to be 1 boy. Then to have two sisters, there has to be two additional girls. That's 3 girls and one boy - which are still 4 children in all.

Of course two parents are two parents for all.

The fewest number of children the parents have is 4

I hope this helps!
