A riddle problem is a question or statement intentionally phrased so as to require ingenuity in ascertaining its answer or meaning, typically presented as a game. Below are a list of the past problem of the week riddles in descending chronological order.
A large truck is crossing a bridge 1 mile long. The bridge can only hold 14000 lbs, which is the exact weight of the truck. The truck makes it half way across the bridge and stops. A bird lands on the truck. Does the bridge collapse?
No, it does not collapse. Because it has driven a half mile - you would subtract the gas used from the total weight of the truck.
