Question: Imagine Johnny, a party clown, is clutching three gold coins, each weighing one kilogram. While walking, he comes upon a bridge with a sign stating that it can only handle a maximum of 80 kilos. The gold weighs three kilos and John weighs 78 pounds. Johnny reads the notice and crosses the bridge safely with all of the riches. How did he pull it off?
