A riddle. (Easy one)
See additional comments.
I will post the answer in 30 minutes on repliers comments unless someone gets it earlier.
You are the bus driver. At your first stop you pick up 29 people. At your second stop 18 of those 29 people get off & at the same stop 10 new passengers get on. At your next stop 3 of those 10 passengers get off & 13 new passengers get on. On your 4th stop 4 of the remaining 10 passengers get off, 6 of those 13 passengers also get off as well & 17 new passengers get on. What is the colour of the bus drivers eyes?
