I think it will be out by tomorrow!!
DeleteWell i found the paper a bit challenging!! it was above the regular level of KVPY paper but well can any one tell me what will be the Cut off Marks for SA stream?
ReplyDeleteI found Maths tough and Physics too. On Aryan website cutoff is 56% i.e. around 45 marks.
ReplyDeleteChandresh
Well I feel I should forget kvpy. scoring poor 25%-30% in exam. Any hope now?
ReplyDeleteNo chance
DeleteDon't worry you can still have the chance!!
DeleteAll the best for next exam,
Pleasee start dicussing paper
ReplyDelete(1) Let x,y,z be three non-negative integers such that x+y+z=10.The maximum possible value of xyz+xy+yz+zx is
ReplyDelete(A)52
(B)64
(C)69
(D)73
I think ans is c
Delete69
Delete3, 3, 4 .. You will get 69! :)
DeleteWat about 3 3 4? U get a higher answer the question is wrng
Delete(2) If a,b are natural numbers such that 2013+a^2=b^2, then the minimum possible value of ab is
ReplyDelete(A)671
(B)668
(C)658
(D)645
C
DeleteC is right
Delete(3) The number of values of b for which there is an isosceles triangle with sides of lengths b+5,3b-2,6-b is
ReplyDelete(A)0
(B)1
(C)2
(D)3
C
DeleteC is right :)
Deletefor b=3.5 , 0.5, 2.0 so D is the right answer
Deleteif we substitute 0.5 in 3b-2 side becomes -ve if i m not wrong........
Delete(4) Let a,b be non-zero real numbers. Which of the following statements about the quadratic equation
ReplyDeleteax^2+(a+b)x+b=0
is necessarily true?
(I) It has at least one negative root.
(II) It has at least one positive root.
(III) Both its roots are real
(A) (I),(II) only
(B) (I),(III) only
(C) (II),(III) only
(D) All of them
B
DeleteD is the answer.
DeleteHow can we say that it would have at least one positive root. When we calculate the roots one root comes out to be -1 and other -b/a
DeleteSee on solving it would come Delta = (b-a)^2
DeleteSo roots are real
and if b>a then one is +ve other -ve
similarly if b<a one is -ve other +ve :D

ReplyDeleteI am getting 67.25 any hopes of clearing ?
ReplyDeletealmost sure.
Deletesanchet
http://www.aryanclasses.com/kvpy/kvpy-13-14/kvpy-13-answer-key.html Aryan classes rocks
ReplyDeleteGetting 67.5 any hopes guys??
ReplyDeletecut off would be 78 for SA stream
ReplyDeleteCut off won't be above 70 last year it was 52
Deleteand i expect 68 . can i clear it
Deletehow come Q.20 answer is c... it shud be d..
ReplyDeleteyes ans 20 shud be d
Deleteit is D
Deleteyes it should be d
Deletei too think it should be d
ReplyDeleteExpecting about 70 % is there any chance ...........
ReplyDeletePerhaps I am also a ntse scholar..........
Please do leave a reply
Here's the reply-
DeleteYou are such a show off..:P:P
And you are obviously getting selected
"perhaps I am a ntse scholar".. you don't know whether you are an ntse scholar or not :P N u will surely get selected. there's no doubt in that...:)
DeleteI don't think fools of your kind deserve to be kvpy scholars. Even after knowing that 70% is more than enough, asking if you have a chance is ridiculously silly. You lack brains and is certainly going to be rejected in the interview. I feel you are in the need of a psychiatrist.
DeleteActually I mean 70 marks....
ReplyDeleteI am getting around 60 + any chance ??
ReplyDeletecan someone please check ans 19
ReplyDeleteit seems that velocity is -ve and acc. is +ve at t=0
and thats the only reason i marked D.a=p-qt
Deleteanswer key is wrong 19th answer is D
Deletei think ans key is wrong
Deleteacc at t =0 cant be determineed coz you dont know what was before it and so u cant find slope of slope
so we'll have to see after t +0 and then ans is B
is 61 actually the expected cutoff?
ReplyDeleteim getting 59.75 any chance?
I think 61 is an exaggeration. And its nothing new. It happens every year. So don't worry. I think you will make it.
Deletei think the answer of Q19 is D
ReplyDeleteanswer of Q47 is A
ReplyDeletewhen will the official answer key declared
ReplyDeleteI am getting 53 marks ! Any chances ?
ReplyDelete50-50
DeleteSure. You will qualify.
Delete70th question is a little bit confusing, is electron moving from lower potential to higher potential or from higher potential to lower potential
ReplyDeleteI am getting around 75 what are my chances
ReplyDeleteYou are a fool to ask this question.
DeleteI'm getting around 48-50
ReplyDeleteAny chances???
Please do inform
You may
DeleteI'm not sure
Let's see what d others think nd hope fr d best
Yes
DeleteSeeing this ppr
U may
Sorry dude But i don't think 48-50 is good enough. This year's paper was a bit easier than the last year and the expected cutoff is around 55.
DeleteI'm getting 45.25
ReplyDeleteany chances??
i'm getting 47.25.. is there any chance?
ReplyDeleteTHE ANSWER TO THE LAST QUESTION (80) MUST BE (B) AND (D) COMBINED AS BOTH ARE INCOMPLETE..
ReplyDeletei agree neither answer is wrong or completely correct
DeleteNo, it is correct check again
Deleteand d can completely explain u the graph
DeleteDeriving from the fact that many thought the paper this year was tougher than last year's, I don't think the cut will go any higher than last year. Comments?
ReplyDeleteWill be under 55 I think
Deletemay be 50-52 though i have not given the test but i have seen the paper
DeleteThis comment has been removed by the author.
ReplyDeleteCan anyone tell answer of 68th question . According to me , it must be c . But answer key says a .
ReplyDeleteYou will have to consider heat absorbed by container also.Then u will get the right answer.
Deletei have scored 52 marks in kvpy 2013 is there any hope for me to qualify it
ReplyDeleteMuch chance you may qualify..

ReplyDeletewhats cutoff
ReplyDeleteI am getting around 54. Will I qualify ??
ReplyDeletecan someone please solve question 23.. ans coming (c)
ReplyDeleteplease some one tell how to do question 67
ReplyDeletei am getting 80, will i qualify????
ReplyDeletei am getting around 54.25. Would I qualify?
ReplyDeletesurely
ReplyDeletecutoff would be 50 to 53
ReplyDeleteplease someone tell wats the answer to ques 15
ReplyDeleteWould cutoff be below 50 or above 50
ReplyDeleteEither abive or below
Deleteneither above nor below
DeleteWhy the hell is the answer to Q.80 (B)????? It's OBVIOUSLY wrong, I challenge you ARYAN CLASSES or anyone else to give a convincing solution to this problem.... You cant do that can you.... and you claim to be able to give coaching and whatnot... can't handle a single bio problem.... No offence... I think the answer is (D), and I am backed by all my Maths and Biology teachers at school... So peace out... :)
ReplyDeleteDoesnt it reach an asymptote ?
Deleteread the sentence .it says increases and then reaches an asymptote ...which means it want to say it reached asymptote on y axis
Deletewhile the figure has asymptote on x axis..
[D] is the correct answer..for sure...verified by resonance, fiit'jee ,Career point etc
No it doesnt.. they are asking for the rate of change of pupulation, i.e (dp/dt), or the slope of curve.. obviously, the slope first increases and then decreases..
Deletei am not a bio student . my additional is stats and i can well guarantee despite what ur fiit jee and stuff says, that the answer is d. it reaches an asymptote. maybe u should look up the meaning of asymptote if u r confused
Deletelet me make something clear.... option (b): Increases and then Reaches Asymptote;
Delete(D)Increases, reaches maximum, then decreases. now continue
Okay, so here is my explanation of why the answer is (D). The question is about the POPULATION GROWTH RATE. Which means the slope of the graph. Draw slopes at some points. Then we find that, slope initially increases to a maximum, and then decreases. I dont care whether it stays constant/reaches an asymptote after it decreases. For all I know, the graph is not big enough for anyone to assume that GROWTH RATE becomes constant in the end. Anyway, I am 144% sure that (d) is the correct answer, I was just trying to help some people out... Thanks
Deleteyup actually both answers are incomplete
Deleteboth shud be accepted
Does anybody feel that the answer to question no 14 should be d (dependent on the configuration of points)?
ReplyDeleteno, because no three points are co-linear.
DeleteExpected cut off please
ReplyDeleteWill I be selected at 56 marks
Please reply for sake of humanity and for sachin
Obviously
DeleteWill I be selected for 48.75 marks????
ReplyDeletePlease tell me....

ReplyDeleteWhat do they mean by 61-66% in the website!!!do they actually mean that 61-66 marks out of 100 is gOnna be d cutoff!!sumone please explain...
OMG
ReplyDeleteWhat do they mean by 61-66% in the website!!!do they actually mean that 61-66 marks out of 100 is gOnna be d cutoff!!sumone please explain...
I think this is based on how much questions were easy to moderate. The cut ofd will certainly be lower.
DeleteHave you seen last year's paper ?
DeleteIt was much tougher they had asked topics like thermodynamic s , aromatic compounds even bio was very tough and the cut off was 52. I am sure cut off this year will be close to 65
What's d meaning of this %???
DeleteDo they mean marks or what do they mean
Please elaborate someone .......
Please
I am getting 53.75 will I make it. Please reply.
