My friend asked me the puzzle,
- A couple have 9 children (none of them were adopted)
- Each child must be either a boy or a girl
- Half of that couple’s children are boys
How that can be possible?
I failed to answer. So, how it is possible?

It's a bit of lateral-thinking, but
if both partners of the couple have children from an earlier marriage, let's say one has four and the other one has three, and they have two children together, then they have nine children in total, but that couple's children are only two, and one of them can be a boy and the other a girl.
The couple have even number of child more than 9 and half of them are boys
If I say, I have 5 apples with me, then it's also true that, I have 4 apples with me, I have 3 apples with me and so on. Thus, the couple have 9 children does not violate that the couple have more children when we take other premises to be true.
