20-11-2008, 12:01 AM
Dear friends ,
CAT fever is over .. End of Battle for this season.. All the best to all puys who rocked this season..
I have tried searching for a thread on Quant for 2009. So i wish to start this thread, and hope it to be the official thread for CAT 2009 for quant section. Mods, please make this a sticky thread so that more threads are not opened.
I would like all quant devils like implex, maskedmenace, prakharc, masoom,varun , vineet and the likes to please contribute to this thread.
official quant thread for cat 2008 was an active thread .. i personally learnt a lot from that.. so lets start:new_bat_angel:
Lets start with the basics and fundas and get set to CRACK CAT 09.

Re: official quant thread for CAT 2009 -

let me start off with the first question..
let f(x) = ax^2 + bx + c where a,b,c are certain constants and a is not equal to 0.. f(5) = -3f(2) and 3 is root of f(x) = 0
what is the other root of f(x) = 0 ?
a)-7
b)-4
c)2
d)6
e)cannot be determined
what is value of a+b+c?
a)9
b)14
c)13
d)37
e)cannot be determined
happy solving:rockedov:
this is cat 2008 question and so elegant solution with less time is required...
ps: i took around 10 min to solve this problem in CAT :sad:

f(5)=25a+5b+c
so,
25a+5b+c=-12a-6b-3c
37a+11b+4c=0
Also,f(3)=0
9a+3b+c=0
a-b=0 or a=b
c=-12a
ax^2+bx+c=0
ax^2+ax-12a=0
So,x=-4 or x=3
So,option(b)
===========================
For the second part,the answer cannot be determined,i feel.
this would have been one of the first few attempts in cat,if i had given it,that is ;-)

I completely agree.its not even 2009  the guys will begin posting once the exam season gets over.Till then,it would not get the required response from the quant champs.also,we might get some unwanted spam from newbies who are abundantly present at the moment.
All the best.

Thanks to rmbt for reopening this thread.
I think we should go by either of the two ways:-
1) Putting up our queries here and helping out each other with various types of questions.
2) Taking one area at a time and moving to the next only when the current one is over and has covered all(almost) types of questions under it.
What say puys?

Good Luck to CAT 2009 aspirants, quant and DI threads at PG helped me a lot.
and you can see my scores..
If anyone needs help, I am just a ping away...
For Quant, i would suggest going through my blog, and my quant sets,
old qqad problems and practice tests.
For DI - OLD mock papers and cat papers, as many as you can get hold of.
Best Regards
Implex
