(#M40000311) ORKUT QUESTION checking wires Keep an EYE

You're an electrician working at a mountain. There are N wires running from one side of the mountain to the other. The problem is that the wires are not labeled, so you just see N wire ends on each side of the mountain. Your job is to match these ends (say, by labeling the two ends of each
wire in the same way).

In order to figure out the matching, you can twist together wire ends, thus electrically connecting the wires. You can twist as many wire ends as you want, into as many clusters as you want, at the side of the mountain where you happen to be at the time. You can also untwist the wire ends at the side of the mountain where you're at. You are equipped with an Ohm meter, which lets you test the connectivity of any pair of wires. (Actually, it's an abstract Ohm meter, in that it only tells you whether or not two things are connected, not the exact resistance.)

You are not charged [no pun intended] for twisting, untwisting, and using the Ohm meter. You are only charged for each helicopter ride you make from one side of the mountain to the other. What is the best way to match the wires? (Oh, N>2, for there is no solution when N=2.)

(#M40010112) ORKUT QUESTION Ration Keep an EYE

Q. 6 guys can each carry a maximum of a 10 day ration-supply; they are on the edge of a desert; so they could all walk together straight out into the desert for 5 days, then return home. That's clear! But not much fun.

Well, in order to make this puzzle possible, they decide on a plan of action to send one of them as far as possible straight out into the desert, such that this "chosen one" can then return home, naturally!

Their plan uses 2 strategies:
1- hiding spots for supplies
2- guys giving supplies to other guys

And to make your life easier, the hiding and/or remitting of supplies is always at day's end, and in "packets" of one-day-rations.

Their plan is also such that in total, the least possible packets have been hidden. A packet weighs 7 pounds.

Finally, the guys walk at same speed: 23 miles per day.

How many miles was the "chosen" one able to go into the desert, and how many "pounds" were hidden?
