One day your entire life would flash in front of you....make sure it's worth watching..

This thread has cluttered up so much by one-to-one posts,someone requesting something to others kind of posts,quoting complete posts while making doubt clarifying posts etc. I kindly request all other to not clutter this thread as much as possible because its hard to find useful posts in between a lot of not useful posts.

Find Range which x can take..
2[x/6]^2 + 3[x/6] = 20.
[ ] --> GIF.

Acc.to me
-29<=x<=-24

Last Aimcat of this season.

Went OK :p

quant-di = 28A/23C/5W=64
verbal-lr = 27A/20C/7W=53 :|
overall = 55A/43C/12W=117 :)

Just one mock-cl proc 11-remaining for me before real CAT on 22nd.

Wishing everybody else a very good luck for "REAL CAT".

Q1.Find the remainder when (12!)^14!+1 is divided by 13!?
Q2.In how many ways a cube can be colored using 6 colors if each color should be used at least once?
Post solution with approach

I
I think it doesn;t make any difference whether n is even or odd.

For both the cases answer will be 2^{(n - 1)^2}

Correct :)
Please explain clearly,how did you calculated that?

Three AP series of 7p + 2 5n + 2 and 35k + 2

first three digit multiple of 5 = 100
first three digit multiple of 7 = 105
first three digit multiple of 35 = 105


last three digit multiple of 5 = 995
last three digit multiple of 7 = 994
last three digit multiple of 35 = 980

995 - 100/5 = 895/5 + 1 = 180
994 -105/7 = 889/7 + 1 = 128
980 -105/35 = 875/35 + 1 = 26

so answer is 90(1095) + 64(1099) - 13(1085) = 154781

actual sum = 154781 + 2 (182) = 155145

how are you getting this 182,shouldn't this be 282?

Q.In how many ways one can fill an n*n matrix with +1 or -1 so that product of entries in each row and each column is -1?
(i) when n is even
(iii) when n is odd

First ever mock in which I scored 125+

quant-di = 30A(25C,5W) = 70
verbal-lr = 30A(22C,8W) = 58 :|

Overall = 60A(47C,13W) = 128

Good sign for me as I am giving CAT on the first day itself

One day I started from A to B at exactly 12 noon. My friend started from B to A at exactly 2:00 pm. We met on the way at five past four and reached our destinations at exactly the same time. What time was it?

Please post approach...

Chillfactor Sir,you are awsome :)
Please solve this and explain it thoroughly :)

PS. Can you give me all of your quant knowledge(brain) for just one day(C-day). I will be blessed then...

Happy Birthday dude!
