I will write a short debrief, points which I feel might benefit others in a chronological order. Background: Engineer from India, 3 yrs Work EX. Target schools : 3 in US, 1 in Europe, 2 in Asia(including ISB) might add more to the list, depending on the time available for Apps and deadlines of various schools. May2006 - -> Took Diagnostic - Pprep1 - 700.(Q49-V35) - -> Identified my Target score as 740+(I am really sad that I could only improve 10 marks from my first diagnostic test that I took offhand) -> Joined TM. -> Didn't do anything after that for almost 6 weeks. Mid June - -> Finally took a date(Aug 17), thinking that it might spur me into action, I was wrong:-(. Idled away my time, just did some questions in OG. July begining - -> Became a bit serious, started taking TM seriously. Found OG10 to be inadequate, but good. I came to know of the wealth of information that is present in TM, from good questions to excellent explanations, I regret being very late in recognising it. If anybody is reading this, then get onto TM and participate in it seriously, it will help you a lot. Second week of July- Serious prep started. S -> Finished OG10, did CR1000(75%), RC1000(50%) and SC1000(10%) -> Got part of Gmat Sets(pdf files)- did them in the last 2 weeks. They are quite useful, especially because they contain some good questions and help you in maintaining your concentration levels for 75mins. -> Got OG11 in the last week, finished it almost 90%. Started taking full length tests by July end. Scores Pprep1 -740 Gprep2 -730 Kaplan1 - 600(I wouldn't advise anyone to take this, I believe that it doesn't mirror the Gmat in any way. if at all you take don't read much into the score) PR1 - 730 PR2 - 700 PR3 - 740 PR4 - 730 Gprep1 -750(second time) Gprep2 -760(second time)on the day before the exam What I did right: 1) After reading some debriefs at TM, I thought that I couldn't neglect Quant, so spent almost 30% of my time on it, especially DS. I believe that the Quant in the actual test is bit tougher than the Gprep one, but if you give enough time for your initial questions, it shouldn't be difficult to score 50-51. 2) Took full length tests with essays, I think it helps u a lot. 3.5 hours of concentration training:-) What I did wrong: 1) Idled away lot of time in the begining, the last one month was too crammed that I couldn't prioritise my time on to my weak areas such as SC. Probably a 2month long sustained prep would have done the trick. 2) My slot was the 5.45PM one. Got in half an hour early as one PC was free. The problem was that by the time I started my Quant section, others were typing their essays, that really distubed me a lot. 3) Took TM seriously only after a long time, till then I would casually go through some posts and that too not on a daily basis. Anxiously awaiting my AWA score, if it is below 5, then probably I may have to take my Gmat once more:-(

Took my Gmat yesterday. Dissappointed by the score. My practice scores were all in the range of 730-760, so I am yet to decide whether to take it once more. Quant section is much tougher than the Gprep one, was able to finish it just in time, and I thought I had not done well in it. Verbal on the other hand was ok for me...but seems like the tables had turned.

Great score safazal. My gmat is in 2 days time:luck2:

Congrats, thats a great score

Congrats, superb score.

Answer is E. Charu, The actual question had one more sentence in it as you said. But this was a variation of it. Actual question: Of the cans of peaches inspected yesterday at a certain plant, 1.5 percent failed to pass inspection. Of the cans that failed inspection, were incorrectly labeled and the rest were dented. If all of the cans that were incorrectly labeled or dented failed inspection, how many of the cans of peaches inspected yesterday at the plant were dented? (1) 450 of the cans of peaches inspected yesterday at the plant failed to pass inspection. (2) 29,550 of the cans of peaches inspected yesterday at the plant passed inspection. OA in this case is D.

E for me. When the line is parallel to y-axis, i.e. a line of the form x = k. the slope is not defined, that means there is no value for the slope, though there are specific values for the angles, namely 90 and 0(whichever way u take it, clockwise or anti) I think this one condition is sufficient to make the answer as E.

Q27: Of the cans of peaches inspected yesterday at a certain plant, 1.5 percent failed to pass inspection. Of the cans that failed inspection, were incorrectly labeled and the rest were dented. How many of the cans of peaches inspected yesterday at the plant were dented? (1) 450 of the cans of peaches inspected yesterday at the plant failed to pass inspection. (2) 29,550 of the cans of peaches inspected yesterday at the plant passed inspection. OA later...

Thanks gjgjgj, I realised my mistake later. Answer should be E.

PR = RT was not given initially, and it took me really long to arrive at the conclusion that answer should be E. Now since that u have specified that PR =RT, ans wer should be A. dilipcrangan, I think we can't solve this without using congruency principles. If we can, then I think it will definitely take more than 2 minutes:)

I would also go with C. If x is always positive and y is always negative then, x - y > x + y

I had answered this question before, but I missed one point in that post. namely, PR=RT. Here Triangle PRS and Triangle TRS are congruent. Two sides and included angle are the same. PR = RT SR = SR, common side. AngPRS = AngTRS Now coming to the statements A) -> z = 70. =>AngRTS = z = 70 So, x = 180 -70 = 110 , A is Suff B) -> y = 40 It doesn’t help us in anyway. So Answer is A.

D. A) if Pel walks at 6.4 km/h or lesser the maximum distance he can cover in 2hrs is 12.8kms. So he needs more time to cover 10*1.6 kms. B)more than 9 mins for a km. let us take it as 9min/km. So in one hour he would have travelled 6.66 kms. 2 hrs -> 13.32 kms. He is still short of 16kms.

I would also go with E. Even if we have the values of z and y, we are always free to alter the line ST without affecting z and y. In effect x can have lot of values as homer_74 as said.

The general method is: if there are n distinct numbers that are used to make all possible n-digit numbers then the sum of all such numbers is = (n-1)! *(sum of n digits)*(11....n times) example: suppose we want to find the sum of all possible n-digit numbers possible with 1,2,4 here, n = 3, sum of n digits = 1+2+4 = 7 (3-1)! * (7) * (111) = 2 * 7 * 111 = 1554 Stucco, I find that your method doesn't work in all cases. take this example itself: 1,2,4 421 + 124 = 545 avg = 545/2, sum = 272.5*6 = 1635 correct me if I am wrong..

Ans C, I think this question is there in OG11.

Agree with stucco, it shud be A.

One easy way out is to plug in numbers and see. We get 2S. Otherwise, consider this: the set of first 'n' integers(say A) can be mapped to the set of first 'n' even integers(say B) as, for every element in A, an element in B is defined as 2A. Example A B 1 -> 2 2 -> 4 3 -> 6 and so on. So if S is the sum of numbers in set A, then 2S is the sum of numbers in B.

Is it 75? Since u said its tricky, I am not 100% sure. OA?

I got it as 1/2 . OA?

I am not 100% sure, Is it (1/2) + (1/2)^3 + (1/2)^5 + (1/2)^7 + (1/2)^9

AngX = AngECD AngECD = AngEDC , angles opposite equal sides are equal AngECD = (180 -y)/2 AngX = 9180-45) / 2 = 67.5

no. of possibilities = 12*10*8*5*2 = 9600 hence, A

edge_, pls have a look at these figures. I think the answer ie E. transyt7 has explained it very well with examples. "The angles can be 90, 90, 120, 60 or 90, 90, 45 and 135...insufficient" 90, 90, 45 and 135 satisfies both the conditions and yet one angle is not 60.
