Question

1) Would this be Mal, Lised Or B'Hon? 2) Would it be 1560, 1650 or 1700

Answer 1

1) The MST will have 3 connections to Mal, more than any other node.

2) The sum of weights is 250 +3*300 +500 = 1650.
.. (You can rule out 1560 as a choice because no weight ends in 10 or 60. This is simply test-taking savvy, not math.)
