I bet you can't get the answer to this in just one minute though you may later get it but not in one minute as required by the time allocated


A girl went to school and the teacher asked her, "how old are you?" She replied I don't know, bt I know that I'm half my mother's age.
The teacher asked, "how old is your mother?" She said I don't know but I know that my Dad is 5 yrs older than my mother.
Teacher, "how old is your dad then?" She said I don't know but I know that if we add our ages, the answer is 10% of a thousand....
Now how old is the girl, her mum and her dad

girl -19yrs, mother - 38yrs n father - 43yrs
