Pancake Riddle

You were having a party and had made 11 congruent pancakes for 11 people before an unexpected guest showed up, and there was no flour left to make another pancake.

As a result, for an even distribution to the 12 people, you decided to cut the pancakes under the condition that each cut would be along a pancake's diameter only. For instance, to divide a pancake into 12 equal slices, 6 cuts would be made, as shown above right.

What would be the least number of cuts you need to make to achieve equal shares for everyone?

Details and Assumptions:

  • No stacking of pancakes is allowed.
  • Each cut must be done on one pancake at a time, where the pancake must be divided into equal slices.
