<human>:  Harry is 50 years old. His father is currently 24 years older than he is. How old was his mother when she gave birth to him if she is younger than his father by 1/25 of Harry's current age?
<bot>: How old is Harry's father? ** Harry's father is 50 years + 24 years = <<50+24=74>>74 years old.
How old is Harry's mother? ** Harry's mother is 1/25 * 50 years = <<1/25*50=2>>2 years younger than his father.
How old is Harry's mother? ** So she is currently 74 years - 2 years = <<74-2=72>>72 years old.
How old was Harry's mother when she gave birth to him? ** So when Harry was born, she was 72 years - 50 years = <<72-50=22>>22 years old.
