Posted on A Fun Zone, the maths-based riddle is a little tricky.
“Halloween was almost over, and Mr Green had less than 20 sweets left. When the doorbell rang, he thought he would give all the sweets away.
“When he opened the door, there were two trick-or-treaters. He wanted to give away the sweets evenly, but he noticed that when he divided the sweets in two, there was one left over.
“At that point, he saw another trick or treater behind the first two. Again, he tried to divide the sweets evenly among the three of them, but again one was left over.
“Finally, another trick or treater came to his door, making it four trick or treaters altogether. Mr. Green still had one sweet left over after dividing the left-over sweets into fours.”
“So how many sweets did Mr. Green have left when the doorbell rang?”
