Hi fellow puzzle lovers!
I have a maths puzzle that is simple but brilliant, and the solution is quite fun. Here it is:
Katie pretends she has a pack of cards numbered 1 to 10,000. She removes every card that has a square number writen on it, leaving a certain amount of cards, N, left in the deck. She then rubs out all the numbers on the remaining cards and renumbers them 1 to N. This step is repeated with N getting smaller after every step.
How many steps are needed until there is only 1 card remaining?
Hope you had fun solving this!
