CAT 2008: QQAD Practice Test Discussions

No, I said with the condition that "If the theory of incharge institute also setting the paper is correct then ...". In my opinion, the cancelled CAT of 2003 has been one of the best till date, and IIM L was incharge that time.

I think what Implex has said is true -> but doubts creep at times when you see CAT 2006 Verbal heavy (knowing B was incharge and they have inclination for Verbal guys), and then C (incharge last year) coming out with ATM kinda quant, and just 2 days before CAT last year, IIM C prof. advising students to prepare DS.

a balanced papr wud b more than welcome....!!!!

but i guess there is also some kind of a cycle involved.. like 05 DI was a bit on the tougher side
06 it was the turn of VA
n the 07 wz all about quant...
so again the turn of DI coming...????

what do othrs feel about it......???

[arun_juee]

Hi,

My Take ( after 2 peg of Smirnoff )

(4+2),(5+1)
(5+2), (4+3)
we can interchange the values of (a,b) & (c,d) n also both pairs among themselves. so 8 cases. in all 24 cases where a+b=c+d
total cases possible=120
by symmetry we can say that (120-24)/2=48 cases where a+b<c+d
so ans is 48

nbanglorekar i did not get your reason of using symmetry in last step of your solution.
Please enlighten me on the same.

there will be 120 combinations in totality out of which 60 will be mirror images of some other 60...
now you get 24 cases where (a+b)=(d+e)
so cases u're left with = 120 - 24 = 96

so out of 96, 48 wud be gud and 48 (ie. their mirror images) will be not so gud...

so 48...!!!!

Now, remaining term i.e. 1/(b+ 1/(c+ 1/(d+....) should be less than 1 and more than 0.5
for which the denominator should be less than 2.
Thus, b can take only 1 value and that is 1.
So b-a = 0

is there any way to check whether 7^1/3 lies between what range.?
how did u come to know that 7^1/3 lie between 1.5 and 2? any method?

Hi,

I would like to thank the PaGal.Guy team as i found the paper "very" well balanced. These papers can bridge the gap b/w the genius and one who is prepared to work hard.

I would also like to know whether such tests are available for DI and Verbal Ability.

Thanks

so option e)

Hi,
Shouldn't the answer this question be (B)

because g(-1)= 1- f(-1+1)
= 1- f(0)
similarly for g(1)

g(3) would render it out of domain of f(x) because f(4) is not defined.
