@habasha : Thanks for the solns @col_do: This is what I am looking on this forum - Shortcuts !!!! Thanks a lot frnd

For Q1. Why haven't we considered integer value = 1. ?? The answer should be D

Hi Friends, Please give explanation for the queries titled: Query 1, Query 2, Query 3, Query 4 and Query5 in the Picasa album Picasa Web Albums - Shyam - Quants

@Goldust : Thanks for the correction. Trying to improve on SC ... I guess I need to do more !!! :(

Well I would certainly go for C . If I were to select options for the first blank space, I would select options A,B and C {Not D because issues are never auspicious and Not E because of the keyword "philosophers called attention to the ---- character of the issue" If we say problematic, there is nothing that is drawing the attention of the philosophers. We never say that "Its a problematic issue", simply because issues being problematic is implicit and there is nothing to mention explicit or drawing the kind of attention mentioned in the statement. What we always mention explicitly about an issue is its nature ! } If I were to select the second blank space, it would be A C , D or E. Deriving common options will lead me to A or C. There is no specific reason for rejecting A, but I feel it should be C. Anyone to correct me over here ?

This is simply awesome friend !!! Thanks a lot for coming out with such helpful applications !!

I am taking a shot at Q 2. We can assume these variables to be actual numbers to simplify solution. Let x = 20 shares and price/share i.e. t = 2 {Its always better to use a number > 1 to avoid exceptional cases.} So x > 20, lets assume the immediate number i.e. x = 21 So first 20 are sold at $(t+1) i.e. $ 3 => Total cost of first 20 = 20*3 = $60 The remaining are sold at $ (t+4) i.e. $6 = > Tot cost of remaining = 1*6 = $6. So the total amt = 60 + 6 = $66 for selling all the shares. Now had we used the same earlier amt i.e. $2/share = > Tot cost = 2* 21 = $ 42. Profit = 66 -42 = $24 If t and x are large numbers i.e. 11 than I guess Profit will be more So the answer is D

I am not if I have got the question right ..... But the question is Roy is now 4 years older than Erik and half of that amount older than Iris And you have taken "Roy is 2 years older than Iris" !!! Any clarifications on this ??

------------------------ For Q 7. I did not understand why it is D !!! Since 2 => a = {3,4,5} and b = {7,8,9} Now from 3 + 6 + 9 + a + b /5 = 6.2 = > a + b = 13 So a has to be {4 , 5} and b = {8,9} Considering each value will only result in Col B > Col A . Please rectify if I am wrong on this one.:)

Hey thanks for the solution.. Wish i cud have answers to all of them !!! I have my GRE exam in 4 hrs from now ... Hope I dont get any questions from above that were unanswered !! :p

no replies frnds !!!!!!!! These are from the monthly threads which contain q's that did arrive in actual GRE exams !!

1 > If an integer is defined as (-1)^n then which of the following is applicable for integers a and b ? i. a+b = a*b; ii. (a+b)= (a) + (b); iii. (a*b)= (a)*(b); A. Only i. B. Only ii. C. Both i and ii D. All the three E. None ------------------------------------------- 2 > If a1 = 2 and an+1 = (an - 1)^2 where n, n+1, n-1 are suffixes. Find a17?

Jesus !!! Thanks a ton to this forum ... otherwise I would have missed so many useful information. Cartman .. can you please explain your answer

Thanks for the explanantion .. these probability problems will kill me for sure !!! :(

What is confusing is the assumption that Jason will first pick 5 blues and 4 whites !!! why can't there be a scenario were he will pick 3 reds and 4 whites back to back ... in that case the 8th one has to be blue !! .. Answer can be even [C] .. Please comment if I have missed on any detail

Q > How Many Two digit numbers have a reminder of 2 when divided by 7 ? {Suppose if the questions asked for 3 digit numbers !!! .. Is there a general trick / formula for such q's?}

If V is the sum of all the even numbers from 1 to 48, inclusive and D is the sum of all the odd numbers. ColA : V ColB : D+23 {How to tackle questions in general which require working on such large data?}

Very much !!! Thanks ruchia !!

Thanks w00t.cricket

Hi Ruchia, Can you please elaborate on ur answer? I found it abstruse !!

Why are we not considering answer as 1 then? Any specific reason?

Hey computer-bot .. Is it possible for you to upload the image on a locn which can be accessed by everyone? I don't have enough posts to view files !!! :(

Following questions are from BB. Please justify the OA. 1 > Picasa Web Albums - Shyam - Quants The figure above shows a large square formed by fitting 3 L-Shaped tiles and one small square tile together. If a rectangular floor 10 feet by 12 feet is to be tiled in large squares of this design, how many L-Shaped tiles will be needed? A : 810 B : 405 C : 270 D : 135 E : 45 2 > A manufacturer packages soap powder in containers of 3 different sizes. The amt of soap powder in a full large container could fill exactly 3 of the medium containers or exactly 5 of the small containers. If an equal number of small and large containers are to be filled with the amt of soap powder that would fill 90 medium containers, how many small containers will be filled? A : 25 B : 27 C : 30 D : 45 E : 54

I will chip in as well !!! Hey All, Is it possible for someone to refer to the DI q's on page no. 418 of BB. I dont have a scanner and neither a pdf file to post the image !!. The DI is titled 'Enrollment, Faculty Size, Faculty Salary and Tuition at College R'. {Test 10: Section 7} Please let me know if it is possible for someone to answers the q's. I kinda got only 2 right and that was a educated guess :( ... So it will be great if someone can explain me the solution.
