# Chains Puzzle

254.3K Views

You have five pieces of chain, each consisting of three links. You want to make one long chain of these five pieces. Breaking open a link costs 1 \$, and welding an open link costs 3 \$.

Is it possible to make one long chain of the five pieces, if you have just 15 \$?

SaintlyZero Pundit Asked on 22nd September 2018 in

Yes,
take one piece and open all 3 links (3x\$1 = \$3)
With those 3 open links you can connect the 4 remaining pieces together. (3x\$3 = \$9)
Total cost \$12 (\$3 + \$9)
