Re: Factorization problem
Honestly, I'd just pick numbers. If 9 is a factor of 2x, let's let x = 4.5, since that's not an integer and likely to mess up the correct answer. Remember, we want one that doesn't HAVE to be an integer, i.e. COULD be a non-integer. Stuart, you're a star! Thank you! Just to confirm, OA is A Picking...

If 9 is a factor of 2X then the following is also true: 2X = 9b where b is some integer. Then (A), (B), (C), (D) and (E) can be rewritten as follows: (A) (6X/54) + (2X/3) ((3 x 9b)/54) + ((9b)/3) = (27b/54) + (9b/3) = 27/54b + 3b which may not be an integer (B) (4X - 18)/9 (2 x 9b - 18)/9 = 2b - 2 (...

If 9 is a factor of 2X then the following is also true: 2X = 2 x 9 x b where b is some integer. X = 9b Just one thing "Gmatman1" 2x = 9b, where b is an integer x can be 4.5, and still satisfy but with x=9b, we are eliminating almost 50% of possibilities You are completely right! My mistak...

The educational theorist says: "But the average homework time for a ten year old, for example, is little more than 30 minutes per night. Clearly, therefore, there is no need to impose the limits these editorials are calling for." This conclusion can only be based on the fact that (D) in mo...

The argument says half of the respondents said they were in the top quarter of the class -> In order for this to be true, the total no of respondents is not equal to the actual class size OR most of the respondents were in the top quarter. So I'll go with A. and I think I'm wrong .. :) - pradeep I ...

This is a simple one.
There should be a direct relation between the word confused and the first word in the sentence after the comma. Only Schliemann can be confused. So it must be (C).

(A) is False. Mr Mead's conclusion is that private ownership will surely not make it financially viable. Ms Gallis does not say this conclusion is correct. She only states that in the 70's price controls were keeping fares unreasonably low. This does not say anything about the financial viability to...

I think it is C because in factual and figure based questions, it is always easy to compute. 500 times daily use = 1500 mg 25% = 34%-9% That is how I would have selected C OA? I would like to let you know that according to other web sites the correct answer is (D). Both nervesofsteel and I explaine...

(A) is False. In my opinion it is very clear why this statement does not weaken the argument. (B) is False. Our knowledge of the underlying mechanisms does not affect reality! The statement does not weaken the argument. (C) is True . This fact would seriously weaken the argument. Extra ingredients m...

(A) is False. The measurement taken in this statement has nothing to do with the marketing director's first measurement. (B) is False. The fact that competitors try to increase sales by making the the information booths more productive does not support the prediction. (C) is True . The important cus...

I cannot agree with hariharakarthi . In my opinion the correct answer is (D). My answer is also supported by the following web site (Q14): http://news.iciba.com/a/20080714/5086.shtml (A) is False. If it would be True then the the percentage of sick people who took 250 mg of vitamin C (34%) should be...
