Even with your explanation of the last weekend puzzle, I had to really think about the symbols and their positioning. It is definitely not the kind of thinking i would normally do. The positioning and the symbol order for the solution did not even cross my mind. Interesting puzzle.I was thinking a numerical solution or some type of inverted or exotic matrix operation.
----------------------------------------Obviously I was way off base. The new puzzle is much easier, It has the form of a classic algebra problem. Thanks for the puzzle. Cheers

Here's the solution to the 'Like father like daughter' puzzle.
Setting up variables: Let F be the father's current age and D be the daughter's current age. Age difference: We know F = D + 50. Ages 5 years ago: F - 5 and D - 5. Relationship 5 years ago: F - 5 = 3 * (D - 5) Substitute and solve:
The answer is 30. Her father is 80. Five years ago he was 75 and his daughter was 25. Thank you for playing! Adri |

Adri, thanks for that little puzzle.
I didn't reply earlier because as I read through the puzzle I recognised the type so when I saw the age difference and the three times as old" I thought "she was 25 then" even before I read the rest of the question to find out what answer was needed! I didn't think posting that before you showed the answer would be appropriate  Cheers - Al. |
