IQ Questions!! #2

This is a bit easier than that 1st one.

You are given 9 standard apples of exactly the same appearance. All of them have the same weight except for 1, which is heavier than the rest. With only a standard balance weighing scale, and using only the weighing method, how would you identify the culprit apple in just two steps?

Step one: weigh 3 on one side, and 3 on the other, setting the other three aside. If they are equal, then the one that's heavier is in the three you set aside. Otherwise, you now have three on the heavier side and you know that the three you set aside do not contain the heavier one.
Step two: Put one of the three that you have determined contain the heavier apple on one side, and one on the other side. Set the third one aside. If the two are equal, then the one that was set aside is the culprit. If not, you've identified the heavier culprit.

BINGO!

Lots of people got the answer but your explanation is the clearest amongst all!

Well, I am a Mensa member.

These two problems have destroyed my sleep, however; my brain is racing and I think my blood sugar is low; I had to come downstairs and eat something.

I made a typo la o.O

Why are you so sarcastic to chris????

[chrishansenhome]

I made the assumption that there was a typo, or perhaps you cut-and-pasted from another source where instead of apples, they used coins.
