@nits2811 Find coefficients of x^4 in the expansion of (1+x+x^2+x^3)^11Is Approach ka koi logic explain karo....
x1 + x2 + x3 + ......+ x11 = 4
Where 0 ‰¤ x1 , x2 ,....,x11 ‰¤ 3
Is the answer to this : 14C10 - 11 ? Please provide the OA

EDIT: I realized that someone has already posted the answer.

in q26 of proc mock 9...
(x^p+1)(x^q+1) is a factor of (1+x+x^2+..............+x^39) where x,p,q are positive integers.
What is max value of p+q?
a)25 b)30 c)40 d)None of these

if we put x=1 won't the max value of p+q be infinity!!
1+x+x^2+...............+x^39 becomes 40
(x^p+1)(x^q+1) becomes 4 regardless of the value of p&q..;

Well its a valid point...but watevar info u have given..is it complete...or may b examiner wld hv forgotten to quote x shldnot be equal to 1...i don't c any other problem i guess...the only way of rectifying this error cld have been by not providing none of these....or giving x =/ 1...

I don't think Question is ambigous...what you are taking is a specific case....max value of p+q should satisfy for all positive values of x(not only 1)....and 30 satisfies for 1 also....infinity won't satisfy for all positive values
2146
@nits2811 this is the complete ques which came in CL Proc Mock 9. they had given the answer as 30 by calculating sum of GP 1+x^2+.......x^39 and then solving for values of p&q.;

i just checked out...may b examiner didn't think this way..he missed out a trick or too here...don't worry...
2148
@michael88 your point is correct.... but i am confused whether the question is asking for max value of p+q which satisfies the condition for all values of x or max value of p+q for any of the values of x.

Puys I usually commit mistake in attempting following kind of questn in RCs,
RC
In this passage, a British novelist and critic recalls a favorite painting.
The first painting I ever bought was by Sheila Fell. I went to her studio in Redcliffe Square feeling uncomfortable and even embarrassed, thinking how awful to be an artist, having to put up with prospective buyers coming to gape, whereas writers never need to see anyone read their books. I kept wishing, all the way up the steep flights of stairs, that I could go and look without Sheila being there. I imagined she must be feeling the same.
I was wrong. Sheila didn't care who looked at her paintings or what they thought of them or whether she sold them. She was perfectly at ease, seemed to me to enjoy showing her work. There was a confidence about how she propped up canvas after canvas that made me in turn relax. I don't know why I'd been so apprehensive – after all, we had Cumberland in common, there was no need for me to explain why I was drawn to her work. What I missed, exiled in London, she missed: the landscape of where we had both been born and brought up.
The painting was of a haystack in a field. The haystack had clearly just been made, it was golden and the field flooded with a red-gold light, the whole atmosphere mellow and rich.
It was a large painting and I realized as soon as it arrived at my home that however much I loved it I had no wall and no room to do it justice. I put it on the largest wall we had in the biggest room and still I felt I was insulting it – the power of the picture was too huge to be contained in our ordinary house. And the light was wrong. The painting couldn't glow, as it wanted to – it needed a vast, empty room and a great distance in front of it. One day, I hoped I'd take it back to Cumberland and find a house there where it could settle happily. But when, after thirty years, we found that house, the painting was failed again. The walls were no bigger and neither were the rooms. So I sold the painting and bought another, smaller Sheila Fell.
It was a terrible mistake. The moment the painting had been taken away I realized how stupid I'd been. So it had been overwhelming, too large, too dramatic to contain in either house but I shouldn't have let that matter, I should have found a way to keep it. I grieved for it and wished I could buy it back, marry it again after the folly of a divorce. But it was too late. And then, in 1990, I went to the Sheila Fell Exhibition at the Royal Academy and there, in pride of place, at the end of the longest room, the room it had always needed, was my painting. Its beauty was stunning. People stopped and stared and admired and I wanted to shout that what they were looking at was mine. I am not at all possessive by nature but suddenly I felt fiercely possessive. This glorious painting had been part of my life for so very long and I didn't seem to be able to grasp that I had willfully let it go.
I went back to the exhibition day after day and on the last became almost maudlin at saying my good-byes, I don't know who own the painting now – it merely said 'Private Collection' in the catalog – but I doubt if I'll ever see it again. In a way, that's better than being able to go and look at it hanging in a public gallery – I'd only go on torturing myself with wanting back. I can see every detail of it in my mind's eye anyway. It lives in my head. I can recite it like a poem, and so in a sense I can never lose it.

The passage serves mainly to
a discuss the influence of environment on artistic achievement
b defend the works of a controversial artist
c explore the emotional context of a particular series of events
d argue against placing undue emphasis on the economic value of art
e recall authors first favourite painting.

could anybdy pls let me knw what are things we shud keep in mind while attempting such questn in RC

Yaar saare questions dede...toh attempt karle..ek question ke liye pura para pad rhe h toh ..baaki bhi attemt ho jayenge...

Rest f the questn fr the above passage:


Q.1
Which statement best summarizes the description of the hypothetical group of people in the first paragraph compared to that of the actual group in the fifth paragraph?

a The first is uneducated, the second had professional training.
b The first slights the artist; the second is overly respectful.
c The first is somewhat intrusive; the second is apparently appreciative.
d The first rejects the artist's methodology; the second praises it.
e The first is sympathetic; the second is grateful.


The last line of the first paragraph – I imagined she must be feeling the same – suggests that the narrator

a believes that most artists feel as she does in the presence of an audience
b is as excited about Sheila Fell's work as she is about her own
c is insecure about promoting her books in front of prospective buyers
d enjoys the company of artists and writers
e is beholden to the prospective buyers.



The central contrast between the first paragraph and the second is best described in which terms?

a Idealism versus practicality
b Expectations versus reality
c Speculation versus investigation
d Anticipation versus disappointment
e Reassurance versus inquietude

The OA is:
1. c explore the emotional context of a particular series of events
2. c The first is somewhat intrusive; the second is apparently appreciative.
3. a believes that most artists feel as she does in the presence of an audience
4. b Expectations versus reality




Now cud u pls xplain the thot process behind questn 1, what i thot was since in the entire passage we are talking about the painting and hw the narrator was affected and felt abt it so I went with option E

My explanations...
1) Luk in the passage the person is talking about painting but if u wld c it also has an added element of emotion attached to it...it uses words like loved it...possessive...she even goes on to say that marry it as if divorced...she is saying all this about a non living thing so she is attached to it...it shows her emotions in a series of events one after the other...now lets luk at each options..
A) It does say one or two thing about the environment but not the main thing...
B) Well it is nowhere mentioned that she is defended some1 or something...
C) In line with what the author says...its a series of events...and also attaches its emotions...
D) Again faulty detail
E) Yes it does talk about the first painting but it is not the main issue...
For these type of questions u need to understand each and every para properly...to confirm the ans re read the first and last paras..and just glance at the remaining paras...
