The answer to the fishing lures puzzle was correct as published. (October 11, 2009) Here's the question again:
"Kevin, Gavin, and Alvin have 36 fishing lures among them. Kevin has 1-1/2 as many as Gavin, and Alvin has 1-1/3 as many as Kevin. What one filch can make them all equal?"
I wrote, "Gavin can swipe four of Alvin‚s lures. (G + 1-1/2G + 2G = 36, so Gavin has eight lures, Kevin has twelve, and Alvin has sixteen lures.)"
The equation describes the distribution of lures: G (Gavin) plus 1-1/2G (Kevin) plus 2G (Alvin, who has 1-1/3 as many as Kevin's 1-1/2G, which is the same as 2G) equals 36 lures.
Which means that Gavin has 8 lures, Kevin has 12 lures (1-1/2 x 8), and Alvin has 16 lures (2 x 8).
So if Gavin swipes four of Alvin's lures, all three guys will have a dozen lures.
