  • A newborn kangaroo, or joey, is born after a short gestation period of only 39 days. At this stage, the joey’s hind limbs are not well developed, but its forelimbs are well developed, so that it can can climb from the cloaca into its mother’s pouch for further development. The recent discovery that ancient marsupial lions were also born with only their forelimbs developed supports the hypothesis that newborn marsupial lions must also have needed to climb into their mothers’ pouches.

    The argument in this passage relies on which of the following assumptions?

    [A] All animals that are born after a short gestation period are born with some parts of their bodies underdeveloped.
    [B] Well developed...

  • Set A consists of integers -9, 8, 3, 10, and J; Set B consists of integers -2, 5, 0, 7, -6, and T. If R is the median of Set A and W is the mode of set B, and R^W is a factor of 34, what is the value of T if J is negative?

    (A) -2
    (B) 0
    (C) 1
    (D) 2
    (E) 5

    Solution

    This problem demonstrates a helpful note about statistics problems – quite often the key to solving a stats problem is something other than stats: number properties, divisibility, algebra, etc. The statistics nature of these problems is often just a way to make a simpler problem look more difficult.

    Here, the phrase “factor of 34? should stand out to...


  • Q) The Chorus from Sam Smith's "Stay With Me" has an eerie resemblance to Tom Petty's 1989 song - “I Won’t Back Down. Mr. Petty and Jeff Lynne, the Songwriters, filed a copyright violation case and settled out of court. Modern song creation has evolved away from the standard process - starting with the lyrics, the sheet music, and finally the tune. For new song creators, it would be impossible to fight cases where some parts of the song had similar sheet music as the songs in the 70s and 80s.

    Which one of the following statements weakens the argument?


    a) According to Muzic82 - an aggregated opinion database from Music Experts, 98% of the experts felt that Sam Smith's song had...


  • Q) Vegan Diet proponents have often claimed that low-carb, high-fat diets integral in a non-vegetarian diet is dangerous, and therefore, they have a superior and balanced diet. In fact, vegan diets lack important nutrients, responsible for brain function and blood formation.

    Which of the following statements support the conclusion of the argument?

    a) Carnosine - a protective agent against aging is found only in Animal Foods.

    b) Vitamin B12, found mostly in meat, and responsible for vital brain functions, is deficient in a Vegan diet with a recent study showing 92% of vegans lacking this crucial nutrient.

    c) There are no conclusive studies to support the theory...


  • Q) If you go by the popularity of Gaming units, as of Jan 4th 2015, Sony’s PS4 sold 18.5 million units and reached 10.9 million PlayStation Plus subscribers, a growth of 37.9% from October 2014.  Despite the massive growth, Sony’s PlayStation is behind Microsoft’s Xbox One, which in November 2014 accelerated its sales due to a $50 price cut, and a bundle of free games. On 28th January 2015, Spotify, the leading music subscription service announced an exclusive partnership with PS4, and offered digital music to 64 million PlayStation Network users. With the announcement, Feb 2015 saw a spike in sales for the PS4 units by 45%.

    Which one of the following conclusions is valid for the above statements...

    If a and b are both positive integers, is b^(a+1) - b(a^b) odd?

    (1) a + (a + 4) + (a - 8) + (a + 6) + (a - 10) is odd
    (2) b^3 + 3b^2 + 5b + 7 is odd

    Explanation:

    The trick to solving this question is to remember that for positive integers:

    (a) Even^(positive integer) = even
    (b) Odd^(positive integer) = odd
    (c) even x even = even x odd = even
    (d) even – even = even
    (e) odd – odd = even
    (f) even – odd = odd

  • GMAT MomentumLike a  tae kwon do blackbelt or an icy road, the GMAT is perhaps most famous for its ability to use your own momentum against you.  Few places is this as evident as on Critical Reasoning questions, in which the most common way to answer incorrectly is to allow your subconscious mind to lead you to a slightly-out-of-scope conclusion that the psychological warriors at GMAC have already anticipated you’d conclude.  Accordingly, to perform well on Critical Reasoning questions it is, well, critical that you...

  • Jay: "#IfObamaLoses trended on twitter for 4 hours on Oct 28th 2012. Therefore, Obama is likely to lose the election”

    Which statement weakens the argument presented by Jay?

    a) #IfObamaLoses was fourth in the twitter trending list

    b) #IfObamaLoses was trending when most of the American twitter users were asleep, hence the twitter trend represents a small minority of active users in the US.

    c) #IfObamaLoses was started by a news channel that is speculated to be the mouthpiece for the republican party

    d) #IfObamaLoses was started as a joke by a well-known democratic supporter

    What is the greatest prime factor of 12!11! + 11!10!?

    (A) 7
    (B) 11
    (C) 13
    (D) 17
    (E) 19

    Solution

    While it is common for students to simply look at the numbers 12!, 11!, and 10! and see that the highest naturally-occurring prime number is 11, it is  important to know that this is an addition problem – the numbers 12!11! and 11!10! are combined to create a new number that may well have a higher prime factor than its factorial components.

    When adding large numbers like factorials and exponents, it is  often quite helpful to factor out common terms. In this case, it’s particularly important, because our...

  • A leading board member of AutoSnip Co., makers of an automated home haircutting system, recently stated that the company was in terrible shape and headed for a disastrous year. His concern was that, since the introduction of the AutoSnip III last year, calls to the customer service line have nearly doubled, indicating that people are very unhappy with the new product. Although it's true that it is the job of responsible board members to raise issues of concern, in this case the board member's analysis of the situation is mistaken. The customer service line handles not only complaints but also sales, and the majority of the new calls have...


  • The function g(x) is defined for integers x such that if x is even, g(x) = x/2 and if x is odd, g(x) = x + 5.  Given that g(g(g(g(g(x))))) = 19, how many possible values for x would satisfy this equation?

    A. 1
    B. 5
    C. 7
    D. 8
    E. 11

    Explanation:

    The easiest way to approach this problem is probably to work backwards, at least until we see a pattern.

    With g(...) = 19, then we can consider which operation applied to (...).  If it was x/2, then (...)= 38.  38 is even so that is fair.   If it was x + 5, then (...) was 14.  14 is even, so that operation would...

  • GMAT 800 Reading Comprehension QuestionConventional wisdom holds that financial markets are informationally efficient—that stocks are always priced and traded at the intrinsic value of their underlying assets. Thus, investors cannot expect to achieve returns consistently in excess of average returns, given information that is publicly available at the time, without taking on large economic risks akin to gambling risks. In other words, one can only obtain higher returns by purchasing riskier investments, and not through expert timing or speculative stock...

Reviews

"I have not reviewed many books for MBA Admission consulting companies but doing it now to give all applicants a brief idea on what the book covers. The book includes 31 top MBA programs - almost all the top schools you have heard or considering for your MBA application. Each chapter is categorized by US States where there is at least one top MBA program. So you have California and Massachusetts with the most number of MBA programs and several states with one top program (Washington, Minnesota, Washington D.C., Connecticut, Virginia, and Maryland) and other states with two to three MBA programs. The book focuses on four aspects of an MBA program - curriculum, cost, class profile and post-MBA salary. For me, the breakdown of the cost and post-MBA industry was useful to make my decision on selecting the top 5 programs for 2017-18. It is a fascinating read in an industry where consultants overprice for their expertise. I recently bought a 30-page guide for $49. Compared to the obvious observation in that book, the 300+ page, MBA in US - the Ultimate guide is a goldmine of information and analysis." - Verified Purchase (21st June 2017)

"I bought the ultimate guide after a friend recommended it for me. The guide covers a lot of ground on the history of each prominent US states and goes into the reasons why a certain industry emerged from each state. In addition to the analysis of the economy, trends and expected changes in the next 5 years, the book features top MBA programs in each state with an extensive study of its curriculum. Ultimate guide is an essential reference book for MBA Applicants if they want to shortlist MBA programs based on value and cost, and not just ranking. " - Verified Purchase (14th June 2017)

"Should be a required reading before applying for an MBA. School events and MBA Tours are PR events disguised as a Q&A. On the contrary, the book is an unbiased analysis of each Top MBA program in the US supported by a large dataset and historical context on each industry. The guide builds a case for indstries that are likely to emerge as favourite for MBA graduates. Thorough and a valuable book." - Verified Purchase (15th June 2017)

"What I liked: The breadth of the information. Some of my favorite nonfiction books have taken the same approach as the ultimate guide have - cover background information in-depth. In the book, the author uses parallel threads to demonstrate the history of the state and the rise of industries. Will make you think how schools thrive based on the policy set by the state. California's obsession with Technology has revolutionized how we do Business and changed post-MBA trends. Many MBA applicants will be consulting or doing marketing for a Technology company. That is one key finding from the book. The latest development in AI, FinTech, and Automation is an additional context that I found valuable in the book.

Very informative. I would recommend that you read the book at least once in chronological order before using Table of Contents." - Verified Purchase (2nd July 2017)
