Thanks to Suman Saraf for recently pointing me to NSA (National Security Agency’s) monthly puzzle blog. Here is a nice and simple problem that they posted in their April blog. Worth trying with your children!
This puzzle created by Andy F., Applied Research Mathematician, NSA
Mel has four weights. He weighs them two at a time in all possible pairs and finds that his pairs of weights total 6, 8, 10, 12, 14, and 16 pounds. How much do they each weigh individually?
As always, please send your answers as comments within the blog (preferred), or send an e-mail to firstname.lastname@example.org. Please do share the puzzle with others if you like, and please also send puzzles that you have come across that you think I can share in this blog.
