Hi Anurag, I anticipate your response.. When we select other values of x (for eg. x=2) the same equation does not give an H.P. Please clarify on how we can convincingly say that a, b and c will be in H.P. Thanks. @ Saketk This question may not be important for GMAT but how about adding value to your...

Hey !! What is the difference anyway between the two solutions ?? At least in this case, both have the same meaning, don't they? You may give it a fancy name like "SLOT METHOD" if you want to.. :) Well, this is mathematics. There is no master formula that is applicable to all or any set.. ...

Hi Anurag, I do agree that when x is assumed as 1, we get an H.P. But the same won't be true for any other value of x. Lets assume x=2 then, 4a(b-c) + 2b(c-a) + c(a-b)=0 4ab - 4ac + 2bc - 2ab + ac - bc = 0 => 2ab + bc = 3ac This is true for a=1, b=1, c=1 which is not an H.P. Alternatively, c(a-b)/a(...

Yes. The 1680 ways includes this sequence and all sequences in which C speaks before A, A before D, and D before F. One must understand that to cancel the arrangements among a particular set of people, DIVIDE the total arrangements possible by the number of arrangements of the members whose ORDER sh...

There are three ships. each carrying 10 passengers. So the first ship could go to any of the ports A, B or C: 3 ways. Second will then have 2 choices. Last ship can go to only one port then: 1 way. Thus, total number of ways of arranging 3 ships to 3 ports= 3*2*1.= 6 (In other words, no of ways of a...

Eight people can be arranged in 8! ways. C|A|D|H can't arrange in themselves.
Thus the number of ways=
8!/4! ( to negate the arrangements made by C, A, D and H, we need to divide the total arrangements by their internal arrangements ie. 4!)
= 1680 Ans.
IMO C.

IMO C. Like Auden. the language of James Merrill is chatty, arch, and conversational--given to complex syntactic flights as well as to prosaic free-verse strolls.

IMO A. Q.3. When hypnotized subjects are told that they are deaf and are then asked whether they can hear the hypnotist, they reply, “No.� Some theorists try to explain this result by arguing that the selves of hypnotized subjects are dissociated into separate parts, and that the part that is de...

Well , I can explain that part. The "It" need not have an antecedent as this It is called the placeholder "it". Usually you will find these "it" usages in the beginning of a standalone sentences. After seeing the explanation I do agree with the OA. Thanks for the reply ...

IMO D.
the only thing to look for here is a parallel structure.
suspected the police "of having"... and.."of using" is correct.
Eliminate A,B and C.
E is passive and thus WORDY.
D is correct.

Hi Pemdas, Can you give a detailed explanation to the above logic ? The percentages are valid for any question involving a normal distribution, and one should memorize them as 34: 14 : 2.
