Mr. and Mrs. Mustard have six daughters and each daughter has one brother. How many people are in the Mustard family?

Although this question seems to require knowledge of mathematics, we actually don’t need mathematics at all.

**Answer** is 9. Because, each girl has same brother. The number of girls does not matter. It doesn’t have to be a boy for every girl. It is enough to have 1 boy for all girls.

Although this question seems to require knowledge of mathematics, we actually don’t need mathematics at all.So 6 girls 1 brother and mother – father. Totaly there are 9 Mustards in this family.

I said 9 but the person who posted it said 9 was incorrect

Same for me.
