Brain Teasers
Pete, Andy and The Lampposts
Pete and Andy were employed by the local town authorities to repaint the lampposts on Main Street.
Pete, an early riser, arrived first on the job and had already painted three on the south side of the street when Andy turned up and pointed out that Pete was supposed to do the north side. So Pete started all over on the north side and Andy continued on the south side.
When Andy finished his side he went across the street and painted six posts for Pete.
There were an equal number of lampposts on each side of the street. Which man painted more lampposts, and just how many more?

Answer
Andy must have painted six more lampposts than Pete, no matter how many lampposts there were. Let us say there were 20 on each side; then Andy painted 23 and Pete 17.Hide Answer Show Answer
