This is a very old puzzle. I remember this puzzle being asked by my Chemistry teacher in Class XI – Dr. Ravi Gopinath, someone was has had a strong influence in my passion for puzzles. I got reminded of this puzzle while having breakfast yesterday with my kids and one of their friends.
Anisha and Arushi need to divide a cake (any shape) between themselves and want the division to be fair, then the process is very simple. One person (say Anisha) divides the cake into two parts which she thinks are equal, and Arushi can pick one. Neither party has a reason to be unhappy and think that it was a fair division. Now they have a friends of their – Nishtha – visiting. They need to divide a red velvet pancake into 3 parts so that each one of them thinks that the division is fair. How do they do it?
What happens when their mom and dad also want a fair share, so there are 5 now? n?
