Steem Riddle of the Week #10: Weighted Balls
Steem Riddle of the Week #10: Weighted Balls
Last weeks riddle was solved by @uber-dragon, congrats to him for claiming the SBD prize! The solution is posted here: https://steemit.com/riddle/@droopy/steem-riddle-of-the-week-9-wandering-monster-solution-revealed-prize-awared
This week, once again, I'm asking that everyone who posts a solution, obfuscate it with ROT13 using this link: http://md5decrypt.net/en/Rot13/ That way others can more easily take part without worrying about spoilers. Only obfuscated posts can win the prize!
This weeks riddle
There are 5 boxes, each with 100 metal balls. The balls all look and feel identical, but one box has balls that way 1.1 ounces, one box has balls that weigh 0.9 ounces and the other three boxes have balls that weigh 1 ounce. You don't know which type of balls are in which boxes.
You have a digital scale that will tell you the exact weight of whatever group of balls you place on it. How can you guarantee to correctly identify which box has the 1.1 ounce balls, which box has the 0.9 ounce balls and which 3 boxes have the 1 ounce balls, using the scale only two times?
Prize
Again, I'm asking that everyone who posts a solution, obfuscate it with ROT13 using this link: http://md5decrypt.net/en/Rot13/. If your comment isn't obfuscated, you aren't eligible for the prize.
The first person to upvote and comment with a valid obfuscated!!!! solution (as decided by me and only me) prior to this post paying out will win 1SBD! The prize will be paid out right after the rewards from the post are paid.
