Here are the two puzzles that I have heard a long ago from my friends.

1) You can touch it with your right hand, but not with your left hand. What is it?

2) 10x+4x = 2y Then, what is x and y?


HINT: (x and y are not numbers)

I think both the puzzles are easy for you.

+1 if only one correct answer. +1 and will mark as accepted answer if both answers are correct.

1) Your left elbow.

2) 'x' means eggs; y is a box of seven eggs.

  • $\begingroup$ +1. You were almost there. Would have given +2 if possible :( $\endgroup$ – AeJey Dec 1 '14 at 11:55

    $\begingroup$ I don't see why this isn't correct. For all we know $y$ is anything that is 7 times $x$. This answer fits all the requirements of the puzzle, and was earlier than the other answer, which was no better than this. $\endgroup$ – mdc32 Dec 1 '14 at 17:35
  • $\begingroup$ @AeJey - This is a good point (thanks mdc32!). Why is Joe's answer more 'correct' than mine? $\endgroup$ – Rand al'Thor Dec 1 '14 at 17:46
  • $\begingroup$ @randal'thor: because, in your answer, 10 eggs + 4 eggs gives 2 boxes of seven eggs, the two boxes are extra, Which were not in the left hand side of the expression making the equation wrong. $\endgroup$ – AeJey Dec 1 '14 at 17:50

    $\begingroup$ @AeJey - So if I'd said 'a collection of 7 eggs' without including the box, my answer would have been right? $\endgroup$ – Rand al'Thor Dec 1 '14 at 20:14
