Natib: for 2nd statement take an example: 8 -- 1,2,4,8 6 -- 1,2,3,6 4 -- 1.2,4 3 -- 1,3 i was also thinking the same way....but if 2 is already a factor of the number than scenario changes.

Answer given by Kaplan: 2. A. (1) Sufficient. Since the quantity 2R is divisible by 3, one of those two factors must be divisible by 3. Since 1 isn't; R must be. (2) Insufficient. We know that quantity 3R is evenly divisible by 3, which means that at least one of the factors must be divisible by 3. The problem, though, is that 3 is evenly divisible by 3, making it impossible for us to determine if R is. But i am not convinced with the answer. 1. when 2R is evenly dividible by 3, means 2R can be: 6, 12, 18, 24, 30 So R can be: 3, 6, 12, 15 How com R is evenly divisible by 3. Please explain..... 2. 3R can be: 6, 12, 18, 24, 30 R can be: 2, 4, 6, 8, 10

We have to support the claim that company should announce the new device after the sales of old device have begun to decline. * New technology often becomes less expensive after an initial surge in sales. --> If a technology becomes less expensive after certain point of time, then buyers would buy the same old technology. Instead of buying the new technology, which may be expensive. So, this choice doesn't support the claim. * Media outlets, such as television programs and magazines, often report on the planned introduction of new devices while the sales of old devices are still strong. --> this choice is strongly supporting the claim that media, TV all play a major role in making people aware of the introduction of new technology in the market that may stop people from buying the old product. * Many consumers are unable to determine whether new technology is superior to current technology. --> does not support the conclusion. * Surveys have shown that some consumers make only one or two technology purchases per year, whereas others make more frequent purchases. --> Out of scope also too weak to support anything. * Consumers tend to be loyal to technology companies whose products they enjoy using. --> this choice does not do anyhting, out of scope.

E and B for me too.

IMO C C What are the OA?

808 Bob Explanation: D is awkward and confusing in that it has two modifying phrases ("carrying as many as seven passengers" and "compared with most sport utility vehicles") between the subject "minivans" and the first verb "cost". Reading the sentence as choice D phrases it, when I get to "compared" I first think it's the verb. Only when I get to "cost" do I realize that the phrase beginning with "compared" is not the predicate but a second modifier. D is confusing also in that it is not clear in what way minivans are being compared with most SUVs. Is the fact that minivans carry as many as seven passengers one of the differences? There is absolutely nothing wrong with choice A. It tells us two things about minivans: Minivans carry as many as seven passengers. Minivans (compared with most SUVs) cost less, etc. Since these two facts have the same subject, we can put them together, without repeating the subject, and inserting "and" between the verbs: Minivans carry as many as seven passengers and (compared with most SUVs) cost less, etc. It would be wrong to put a comma in front of "and". On the other hand, the comma after "and" makes perfect sense: it's one of a pair of commas setting off the modifying phrase "compared with most SUVs". Beware those OAs! They are not always correct!

Yep it is C.

I also went for B. Please help us understand how D is better than B?

confused between B and D. but yes "their" has no clear referent in choice D. So will go for B.

i think A. What is the OA?

Agree with amitabh. should be C. ksgill, if we combine and solve the above two statements, we wil get that y has to be greater than 0. so x > 0. as mentioned by amitabh above.

yes should be B. same explanation as given by flex_many

Agree with OA. Is SQRT [(x - 3) ^2] = 3-x ? (1) x does not equal 3 (2) - x |x| > 0 |x-3| = 3-x if (x-3) x 1st, Insufficient 2nd, sufficient

gud explanation by ankitarish. Agree with E.

yes should be C.
