William has 5 children. Plus Gretchen has 5. There are 10 children altogether. 5 of them are boys.

• Dude

Nope, sorry that is not the solution here. There are only 5 children total, and half of them are boys.

• Andy

It feels like I am stretching a bit;

Gretchen has four children – two boys and two girls.
William only has one child – a boy.

So five in total. However, William’s child is also one of Gretchen’s boys – so only four unique children, two boys and two girls.
