I find this approach most convincing so far! Thanks.

CassieY, Yes the OA is correct -39¼ can be scored by 0 correct and 157 Wrongs ..rest unanswered.

DISCLAIMER: This is NOT GMAT Q. Looking for any help from people... An examination consists of 160 questions. For each correct answer, a student earns 1 mark and for each wrong answer, a student loses 1/4th of the a mark. Find the number of distinct net scores that a student could earn in the examination. i) 790 2) 797 3) 795 4) 801

S= 1(2) + 2(2^2) + 3(2^3) + ... ..........+ 100(2^100) 2*S= 1(2^2) + 2(2^3) + 3 (2^4) + ...................+ 100 (2^101) In 2*S and S match and subtract the terms with same values of 2^n we get, 2*S - S = last term of 2*s - first term of S - [g.p of 2^2 + 2^3 ....2^100] => 100 (2^101) - 1 (2) - [2^2 + 2 ^ 3 + ......2^100] S = 100 (2^101) - 2 (2^100 -1) S = 100 (2^101) - 2^101 + 2 => S= 99(2^101) + 2

hey 12rk34 ..out of topic question. How do you type that radical/root sign? :) oh .. I think I got it .. ALT Codes - Alt codes for Mathematical Symbols

Shooter, (A) He ate ten pizzas, bringing the count to thirty. Is correct sentence because 'bringing' is modifying the whole preceding clause.In this sentence He is not bringing the count down to thirty. This whole preceding act (He ate ten pizzas) is. (B)They were inside the building, having the magical powers. Here reference for having is ambiguous. The sentence needs to be re-written to convey the correct meaning. The sentence (A) has no ambiguity, but sentence (B) has. Besides, please go through this post. Some good expln given by 800bob for "ing"/"ed" phrases.

Area of a ||gm = Multiplication of two adjacent side * Sin(Angle between them) => 6* 6* Sin X = 18 => Sim X = 1/2 X can be 30 , (180-30)

30? 6*6*sin X = 18 X can be 30 , 150

I feel E Cannot be the answer because the Q asks "likely to be damaged" Commuters who do not live near public transportation routes will not get advantage of new plan BUT they will also NOT get damaged.

Imo A

One often hears that biographies are autobiographies, that the biographer is always writing about himself. On the contrary, serious biographers seek and welcome the unfamiliar, however troublesome to account for. Ron Chernow, the author of rich biographies of the American businessmen J.P. Morgan and John D. Rockefeller, remarks that biographers "like to stub their toes on hard, uncomfortable facts strewn in their paths." Such encounters with the unaccountable are opportunities for breaking out and breaking through, in new directions, to fresh understanding. One also often hears that biographers must like their subjects. That would of course rule out such vastly important subjects as Hitler or Stalin. In practice, the biographer must like the subject not as a person but as a subject. Some are good subjects for the author, some bad. And what makes one subject better than another for any particular biographer varies dramatically. Some of the reasons are purely practical. Does the subject need a biography? Are the materials available? How much time is needed? A biographer's knowledge and ability also determine the choice. Great scientists are great subjects, but can one write about their achievements with insight and authority? Personal idiosyncrasies matter, too. Biographers tend to be attracted to subjects who display particular personality traits, whether they be ambition, cruelty, ingenuity, or any other characteristic that separates a potential subject from the multitudes. In choosing a subject, the biographer's main question should be, "Can an effective book be made out of this person's life?" Day after day for years, the biographer will try to untangle chronology, compress relationships without distorting them, and keep the main narrative clear while carrying forward several intricate strands of the subject's life. What pushes most biographers on in this endeavor is not necessarily affection for the subject but the feeling that they are writing a good book. It can be inferred that the author makes which of the following assumptions about biographies? A. Their main purpose is to inform readers about key aspects of the subjects' personalities. B. Only subjects who share traits with biographers make good subjects for biographies. C. Compelling biographies cannot be written about ordinary citizens. D. The biographer's credibility with readers is a factor in the critical success of a biography. E. Practical considerations are most important in the selection of a subject for a biography.

I really doubt the OA . The answer has to be E. What is the source ? genius_in_the_gene, You cannot conclude c>d unless you know the sign K and L Shobby, greater x intercept => greater y intercept -- is INCORRECT. Imagine two parallel lines cutting Quad I II and III. In that case, the line with greater x-intercept will have smaller y-intercept. Point to be noted is that x-intercept is sign sensitive !

I too picked D. :( But OA is C.

Here is the another Q with exactly same structure. The credited answer is C. So, I think then the Ans for this (Sprained ankle Q should also be C)

Collection of 800Bob's explanations: Adhamjon's SC notes - eSnips, share anything

It has to be A, absolutely. I disagree with the OA if it says B. .

I am still with A.

B makes sense if the Q stem would have asked "What can we logically infer from the above stimulus?" But the Q is "conclusion follows logically if which one of the following is assumed?" If we assume option A which states that X ONLY IF Y. X: "People can feel secure " ONLY IF Y: "know for certain whether their actions are legal." If Y is the necessary and sufficient condition. If NOT Y --> NOT X. Where am I wrong

IMO A. If A is assumed "People can feel secure only if they know for certain whether their actions are legal.", then we know for sure the "people cannot feel secure". If we assume B, there is still an element of 'might', people might feel secure or they might not. But we need to conclude that they cannot feel secure. What do you say Shooter?

Shooter ~ Do you think so coz of the the word "demonstrate", which can mean to show by example or illustrate and not necessarily imply relation to people and their reaction. ------------------- What will you guys answer to this? Which of the following is the primary reason that the author mentions the work of N. Scott Momaday? (A) To illustrate how the author believes that members of the Native American Renaissance have broadened their potential audience © To demonstrate the traditional Native American oral appeal of contemporary literature.

OA is A, indeed. I think I misunderstood because of the language used in option C. .. "contemporary appeal of" Option C means exactly opposite of what passage is conveying. Isn't it?

The outpouring of contemporary American Indian literature in the last two decades, often called the Native American Renaissance, represents for many the first opportunity to experience Native American poetry. The appreciation of traditional oral American Indian literature has been limited, hampered by poor translations and by the difficulty, even in the rare culturally sensitive and aesthetically satisfying translation, of completely conveying the original’s verse structure, tone, and syntax. By writing in English and experimenting with European literary forms, contemporary American Indian writers have broadened their potential audience, while clearly retaining many essential characteristics of their ancestral oral traditions. For example, Pulitzer-prizewinning author N. Scott Momaday’s poetry often treats art and mortality in a manner that recalls British romantic poetry, while his poetic response to the power of natural forces recalls Cherokee oral literature. In the same way, his novels, an art form European in origin, display an eloquence that echoes the oratorical grandeur of the great nineteenth-century American Indian chiefs. ----------------------------------------------------------- Which of the following is most likely one of the reasons that the author mentions the work of N. Scott Momaday? (A) To illustrate how the author believes that members of the Native American Renaissance have broadened their potential audience (B) To emphasize the similarities between Momaday’s writings and their European literary models © To demonstrate the contemporary appeal of traditional Native American oral literature (D) To suggest that contemporary American Indian writers have sacrificed traditional values for popular literary success (E) To imply the continuing popularity of translations of oral American Indian literature IMO C. He mentions Momaday's work to convey that the oral tradition is still reflected in comtemprorary works. But OA is not C.

IMO B. Agree with hina's explanation.

Per the Q, the below is

D looks good.
