Induction Puzzle Definition

It might help you to know what’s induction puzzle. I’m giving you the Wikipedia definition here for you –

Induction Puzzles are logic puzzles which are solved via the application of the principle of induction. In most cases, the puzzle’s scenario will involve several participants with reasoning capability and the solution to the puzzle will be based on identifying what would happen in an obvious case, and then repeating the reasoning that: “as soon as one of the participants realises that the obvious case has not happened, they can eliminate it from their reasoning, so creating a new obvious case”.

A man bumps into his mathematician friend on the street that he hasn’t seen in 5 years. The man asks the mathematician how old his children are.

  1. 6,6,1
    as he knows mathematician has children not a single child and mathematician specific said that his youngest “child” have blue eyes. that remove possibility of 9,2,2 because his statement gives information that there is no younger twins.

  2. Solution for above problem is: [4,3,3], because product of three number should be 36. sum of three number is 10 windows.

  3. Hi all
    My Solution: 1,6,6
    The other solutions like 2,3,6 (11 Windows) or 3,3,4 (10 Windows) are definite, so he wouldn’t ask for an extra Piece of Information. Only with 13 Windows There are 2 solutions:
    So he Must Ask for More Info and in saying there is only 1 youngest defines the Solution.
    Happy easter, best wishes
