Okay gotcha... So when you factor 26^4 out of (26^4 + 26^5) you get 26^4(1 + 26) = 27(26^4). I missed that factoring step for some reason, thanks for the reply!

All of the stock on the over the counter market are designated by either a 4 letter code or 5 letter code that is created by using the 26 letters of the alphabet. Which of the following gives maximum number of different stocks that can be designated with these codes ? a. 2(26^5) b. 26(26^4) c. 27(26^4) d. 26(26^5) e. 27(26^5) SPOILER - OA is C I understand it is 25^4 + 25^5, but how does that become 27(26^4)?? Any help is much appreciated!

Hey all, Just heard through the grapevine that someone I know who took the exam in the past few weeks got 10 probability questions in his quant section! His score ended up a little above avg (I think high mid 500s) but I think he was really thrown off by the number of prob questions. It seems the rule of thumb has been you will get maybe 3-5 prob questions at worst, so his experience was definitely an abberation from the norm, but thought I would pass the word along to all of you anyways! The odds that it will happen to you are very low, but I thought everyone would want the heads up. Good luck!!

IMO E. Can't be D because it makes it seem that Madagascar is an ideal site for researching because it was settled by humans, when really the reason it is ideal is because it was one of the last places to be settled.

I'm going to check it out - thanks for sharing!

IMO it is D. We can't use between because that should be designated for two items, not a list of multiple items. E is passive while D is succinct and correct. Plus a balance among sounds a little redundant to me...when one is referring to a balance it is already implied that he is referring to multiple things.

I believe that the answer is E. The question is essentially asking whether or not the 10s digits sum to a number greater than 10 OR whether the digits in the hundreds column sum to a number greater than 10. In either of these situations, the hundreds digit in the sum would not equal the sum of the hundreds digits in the two numbers. Stmt 1 answers our question about the 10s digit, but provides no insight into what the digits are in the hundreds column. We know that there is no number carried over to the hundreds, so if the digits in the hundreds column sum to a number less than 10, we will be able to answer Yes to the question. However, if the two digits sum to a number greater than 10 (ie 999 + 999 = 1999), the answer is No. Stmt 2 does not provide any help. IMO E

E - not enough info about coffee. The question states how many people who dislike tea dislike coffee, but says nothing about how the students who like tea feel about coffee. Therefore, you can't make any conclusion on the total number of those who like coffee.

IMO - A. B, C - Reversion back is redundant D - "to raise" doesn't work here E - "reversion into" doesn't work either

I believe it is E, B, C. For Q2, you would only use "aim at" if you were referring to aiming at a target. If you are trying to accomplish a goal or objective, you aim to achieve it, not aim at achieving it.
