Waterjugs? Gestalt!

We're going to do a fun little experiment today, and y'all are the test subjects. This is a test of the human psyche, so... enjoy!

I'm going to give you 10 short problems, each the same idea. You have 3 jugs of different sizes, and you want a certain amount of water in one jug only. You have to say what you'd do to get the desired amount.

Here are the rules for this experiment: You have to do all ten and you must do them in order; you can give up on any question if you can't figure it out, but take your time; and you need to identify how you did each one. Then, please put in the comments what the answer you got was, about how long the questions took you [individually or total, it doesn't matter], which question was the hardest, and which question was the easiest.

Here are the examples:
The first three numbers in each set are the jugs' capacities; the last number is the amount you want to get.
  • 1) 21, 127, 3 = 100
  • 2) 14, 163, 25 = 99
  • 3) 18, 43, 10 = 5
  • 4) 9, 42, 6 = 21
  • 5) 20, 59, 4 = 31
  • 6) 23, 49, 3 = 20
  • 7) 15, 39, 3 = 18
  • 8) 28, 76, 3 = 25
  • 9) 18, 48, 4 = 22
  • 10) 14, 36, 8 = 6
Good luck, and feel free to pass this along to your friends. I want to get as many people answering this as I can; I'll post the answers and some comments later on in the day when I have a chance and after a lot of people have answered. Try not to read other people's answers and comments until after you've answered all the questions...!

You'll find the results fascinating - I know I did, and the two people I just tested it out on did as well. What are you waiting for?! Start!
