A girl went to school and the teacher asked how old are you?
She replied I don’t know but I know that I’m half my mother’s age.
The teacher asked OK how old is your mother?
She said:- I don’t know but I know that my dad is 5 Years older than my mother.
The teacher, then ask how old is your dad?
She said I don’t know but I know that if we add our ages the answer is 100 yrs…
Now how old is the girl, her mum, & her dad?
