I think I have realized my mistake. The approach was right I guess, except that I missed: 8P2/2! which gives me my answer.
Never the less I would like to see other approaches to the question.
Thanks.

So this implies, (and as I have edited the text reply above) I can have a certain scenario where in according to a certain rule, n arrangements out of 6 arrangements are good, we can derive the answer from:-
7! x n/3! = ans? right?
Thanks,

Notice that, of the 6 arrangements, only arrangement #4 follows the rule about A before I and I before 0. From this, we can conclude that 1/6 of all arrangements will follow the rule. So, of the 5040 arrangements, 1/6 follow the given rule. 1/6 of 5040 = 840, so the answer is A Hi Brent, You made i...

The source is RC99-Aristotle. My line of thinking is, when people find out they cant use the device as desired, they start doubting themselves. Does putting their intelligence in question, as a result of this stretches the argument a bit too far. I was looking at this question more from cause and ef...

What I can advise is that the first thing you do is read only a few first sentences of each paragraph to have a general picture what each paragraph is about. It is a good idea also to note down the function of each paragraph and whether it for example contradicts or confirms what is stated in other...

Hi, I have been practicing RCs for some time now, and also analyzing the mistakes. But I have been not able to achieve the required confidence to go behind me.
