OK.
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.

Great!

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,
Vaibhav.

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...

But I cannot understand where in the passage it states that the heart of sea snakes is located at the midpoint of their body?

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...

Ergonomics vs Technology

A cause of fatal mining accidents was once the peculiar configuration of the controls on the trams shuttling along mineshafts. Each tram had a steering wheel that rose straight up from the floor, with a brake pedal on one side and an accelerator pedal on the other. There was no room to turn the tram...

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...

IMO E.

Because it is very obvious and coming straight from the argument; while other aren't.

I find that very cumbersome and distracting. - Yes, I always make it a point to read the whole text before I start ...

Not getting em right enough

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. There are still 3 months to go for my GMAT. (Feb-2013) I would need more practice and hence more material to pick GMAT like passages. I am a...
