IQ Brain Teaser #127
The house on the far hill is more than 50 years old. It caught fire 24 years ago when some kids were playing with matchs. Fortunately the fire department, which had only been around for 37 years prior to the fire, showed up before too much damage was done. Come to think of it, the Chief of the fire department helped build that house 5 years after he joined the department. He joined 3 years after he got out of the service. He was discharged just 1 year before the department was founded. Given what I've told you, tell me how old that house is.
