KenKen Puzzle Number 24: Using a tree diagram to clarify the logic

In this puzzle we employ a tree diagram for the first time to see the logical possibilities more clearly.  The 3 on top can combine with 2 or 4 in a 1- cage, and we can show how these possibilities combine with other numbers in a column to arrive at the column total of 15.  Check out the solution below to see this tree diagram at work!

 

 This is Inky #1 from Hard 5x5 Inkies by Krazydad, Volumn 3, Book 8

 And here is the Solution for Puzzle 24 of our Series
