the 1st ball can go in any of 3 boxes so 1st ball has 3 choices.
similarly 2nd ball can go in any 3 boxes, so again 3 choices,
so for all the balls its 3*3*3*3 = 81

Is n > 6? 1) sqrt(n) > 2.5 2) n > sqrt(37) OA is D. I was thinking the answer should be A because n > 6 or n < -6 and n > sqrt(37) would still be true, thus we don't know if n > 6. Please help. The Logic is Sqrt can never hold a -tive number atleast in GMAT. so Sqrt-2.5 * Sqrt-...

Hi I still somehow disagree with this answer. here is the structure of the argument Premise : Company X conducted a taste test to determine whether its new soft drink had a good chance of commercial success. A sample of consumers was asked to compare the flavor of the new soft drink to that of an es...

Hi Saw this Question in MGmat challenge set. For a particular company, the profit P generated by selling Q units of a certain product is given by the formula P = 128 + (-Q^2/4 + 4Q - 16)^z, where z > 0. The maximum profit is achieved when Q = (A) 2 (B) 4 (C) 8 (D) 16 (E) 32 Now I understand the w...

Sorry for opening up the thread, but I still don't understand something, and its pretty fundamental, that I cannot do under-root of anything in this entire statement for eg i cannot do a undr-root of 12 as it may be 6or -6 and on left hand side I cannot do an under-root of x^2 /9 as I don't know wet...

Sorry Tim,

by under-root I meant Square root
I understand that exponent with even powers have hidden base, therefore I am confused with this question.
if you can clarify, and also if you can point me to some post/article as to where I can square root something in Gmat conditions

the basic assumption here is- the number of times the company will be featured in the press is proportional to the company’s revenue. the statement E here gives a reason of high sales volume this Yr, but it never tells anything about higher/lower sales volume in next yr.. how does this undermines ne...

E totally does this of course, because it shows the introduction of new product lines that could have increased revenue but may not have been of any interest to the fashion press.

Ron: even though I marked this correct as E, in sentence A, B and C, is the usage of Which incorrect? the way I thought was that "Which" is incorrect as the whole sentence "which was determined by when the sun reached the observer's meridian and differing from city to city" acts ...

I understand why C is correct, but can you please answer my query here? in sentence D I think use of "are looking to use its " Its is singular hence incorrect, am I correct in my understanding? and also is there anything wrong with "waterfront as a way of improving" ? Thanks Nikhil

People say, that E is perfectly parallel, however i ruled out E because as per me "that few people have...X or HAVE made..
I think the second have is missing, how do we justify that?

Thanks,
Nikhil

I got this Question In my verbal prep The stars, some of them at tremendous speeds, are in motion just as the planets are, yet being so far away from Earth that their apparent positions in the sky do not change enough for their movement to be observed during a single human lifetime. (A) The stars, s...

This has been amply explained earlier in the thread. Check it out.

Thanks
