Guys,
Let's get to business then..
Here's my first contribution to this thread..

Fact, Opinion, Inference
by Richard Grzeskowiak
A fact is a statement that can be verified. It may involve numbers or dates.
The truth of a fact is beyond argument.

Example: There are 24 people registered for English 152, Section 3, this summer.

Example: A football field in the US is 100 yards long.

Example:Helen Hayes, the First Lady of the American Theatre, died on March 17, 1993, at 92 years of age.

Expressions of personal likes or dislikes are erroneously often called opinions.

Example: Dawn feels sports medicine is the field to be in.

Example: I like chicken fat ripple ice cream.

Example: Lisa enjoys jazz more than rock music.

Example: My husband looks great in the nude.


An opinion is an informed judgment based on facts, an honest attempt to draw a reasonable conclusion from evidence.
It is arguable--a contestable statement.

Given the same truthful information, another person may come up with a different conclusion (opinion).

Example:Because the Cold War is over, we should dismantle the US defense forces.

we should scale back the US defense forces.

we can now concentrate on aggressively controlling Third World despots with US defense forces.

An arguable opinion, then, needs
a thesis statement, a claim, a proposition to be supported, which deals with a matter of probability, not a fact or a matter of taste.
an audience to be convinced of the thesis
grounds, specific reasons, that support the thesis.
Here's a test to see (hear, feel) whether you have an opinion:
"What makes you say (write) that?"
If the answer reverts to "I" something-or-other, then it is not an opinion, but a statement of taste.
A writer (speaker, doer) implies.
A reader (listener, onlooker) infers.


To imply means
to convey or communicate not by direct, forthright statement but by allusion or reference likely to lead to natural inference.
to express indirectly
to involve or suggest by logical necessity.



To infer means
to conclude from evidence; deduce
to have as a logical consequence. (an inference = a conclusion)
Example: I see leaves turning yellow on a small tree. I know it is July 11th in the middle of the summer. It hasn't rained in 2 months. I infer (deduce, conclude) that the tree is stressed.
Example: I hear water running in the house.
It's downstairs because I am in the upstairs bathroom. No one else is up yet. I conclude a pipe has burst, or someone is using my water from the hose, or the burglar had to wash her hands.
Then I remember the power outage. Now the running water makes sense because the water softener is out of cycle and using water during the early day instead of the middle of the night.
Basic to interpretation is inference-making. An inference is a conclusion or judgment which expresses some significant attitude suggested by what is seen, heard, or read. We see the sky clouding up and infer that rain is coming...
Sometimes a single observation may trigger a chain of inferences. Thus Robinson Crusoe saw a footprint and inferred (1) that somebody else was on the island, (2) that there was a possibility of danger from that person, (3) that he should take precautions against that danger. In all such instances the thing observed becomes a sign of something, and the inference interprets that sign.

A few questions on QA..

1) If 7x+11y = S has EXACTLY 4 solutions, in which both x and y are positive integers, what is the minimum value of S?

Sol:

First idea that should strike is 'S' should lie between : 3*77 to (4*77-1)

We can write above equation as :
x= (S-11y)/7
Since the question is about minimum value of 'S', y-->1

Hence,

x1 (first sol) =(S-11)/7
x2= - 11 ( 'x' follows an AP with 'd' = -11)
x3= - 22
x4= - 33

Now, x4 should be 1 as min(S) is asked..

- 33 = 1
S=249

corresponding pairs will be (34,1) , (23, , (12,15) and (1,22)

Puys, Please let me know if there is any conceptual flaw in this solution!

Also, try out the following Questions :

Q1) If 7x+11y = S has EXACTLY 4 solutions, in which both x and y are positive integers, what is the MAXIMUM value of S?

Q2) If 7x+11y = S has EXACTLY 4 solutions, in which both x and y are integers, what is the minimum/maximum value of S?

PS: It's always better to frame 'n' solve 2-3 questions from your side from a given question. It helps in learning Concepts to a better extent!

Regards,
Saurabh

Hi puys,

My take on this problem

Given equation

7x+11y=S
can be written as a series of eqns as follows

7x+11y=S
7(x+11)+11(y-7)=S
7(x+22)+11(y-14)=S
7(x+33)+11(y-21)=S

We need a positive value for y.therefore y minimum value is 22 and x=1.please note that x can be any value i want it to be because everything else adjusts itself automatically.Hence 1,22 ;12,15 ;23,7; 34,1

Please note that this can be applied to any equation and any number of variables...Just try out the same question for 7x+11y=S for 6 solns and try it out..

I think this sum has got its deserved closure once and for all... :P

Hi All
Here's another one to recharge yourself.
Details for meet on coming weekend:

Date: Sunday, 27th September 2009
Venue: CCD, IIT Chennai
Time: 5pm
Agenda: As per majority demand AIMCAT1010 discussion, which was one of the toughest till date. hari to help out/lead for VA, myself and naga sharing DI/QA. And of course with assistance/inputs from all others. We'll probably look into some individual questions or concepts from the immediatley previous SIMCAT/ProcMock also provided time permits and there is no one yet to take up the test. I'll be bringing 1 copy of AIMCAT1010 and ProcMock5. If some others can also bring 1-2 copies of AIMCAT it'll be easier to handle all 3 sections. And SIMCAT also if time permits and a discussion on that is asked for.
P.S: Newbies plz PM ur number to me/hari/naga so that we can get in touch with you.

7x+11y = S

x = S - 11y/7

now here for x to be integer , y should be multiple of 7

since 4 solutions are given,

y = 7,14,21,28

minimum value is therefore --> 28*11 + 7 = 315

ps :reason i got 319 yesterday was that i calculated as 28*11 + 11 = 319:banghead::banghead:

Yes, S= 172

when x(at minimum) = 1 y= 15 (add coeff of x) ; Solution =172
x(add coeff of y)=12 y=8 (add coeff of x) ; Solution = 172
x(add coeff of y)=23 y=1 ; Solution = 172

og11 and og12 ---> official guide for gmat - 11th edition and 12 edition

Thnks naga and Would by ne chance hav sft copy ?? ...

I remember this question appearing in one of the previous AIMCAT paper and also discussing about it.

Minimum of x would be 1 and similar with y.

For solutions:

x = 1, 12 and 23 (adding the coefficient of y, viz 11)

y= 15, 8 and 1 (adding the coefficient of x, viz 7)

Minimum value would occur at x=1 and y=15 thereby giving 172

Not very sure of the solution but the approach is somewhat related to the explained.

cubes can even come in cat but then not as direct type question.. something like one which came in 1009 ..as di section of cat is moving towards reasoning
based di, cubes might be one of the ideas for question setters , u never know..

ps: hari , this is strictly not for u!

use og12 guide for verbal prep if at all u r preparing for verbal section... this year cat will have more likely gmat like rc's as its an online exam... ofcourse jus an assumption from ma side.. but then og11 and 12 are too good to read for a person weak in verbal like me

og11 ?? og 12??

I am pretty sure that this kind of cube sums would not appear in CAT but in other exams.

Having written mock snap and the-like exams many times, I have seen a trend of the 'painted cube' problems.
I am pretty sure that this kind of cube sums would not appear in CAT but in other exams.

To generalise,

the no. of cubes will have only one side painted : 6(n-2)^2
the no. of cubes will have two sides painted : 12(n-2)
the no. of cubes will have three sides painted : 8 (obviously the 8 vertices)
the no. of cubes will have no side painted : (n-2)^3


Let cube have an edge of 8 and cut into 2 cm each.
Therefore n=4;

one side painted = 6(n-2)^2 = 24
two sides painted = 12(n-2) = 24
three sides painted =8
no sides = 8

Thanks for the explanation bro! :)

i have a doubt.. Isn't there any approach to find the smallest common no (113, in this case) that satisfies the condition?

there are few methods for that ..check out in TG website.. but then i wont suggest u to take that adding the number getting the two series takes hardly 2min at the max

Again before the meet if roles each person has to play can be decided it'll be great. Hari...Each section handled by 2-3 people scoring high consistently?(Again thanks to iamnutty for the suggestion )

But first let's get organized or under one umbrella/mailing list. Do PM the mail id's to him so that we can go ahead and plan next step before meet on Sunday.

first take any two condition , i always prefer big numbers

11b + 3 = 13c + 9

divisor of 13 + 9 = 9,22,35,48,61,74,87,100,113,126,139

divisor of 11 + 3 - 3,14,25,36,47,58,69,80,91,102,113

so smallest number is 113

whats the next number then ?

its of form LCM(11,13) + 113 = 143k + 113


hope this helps....

Thanks for the explanation bro! :)

i have a doubt.. Isn't there any approach to find the smallest common no (113, in this case) that satisfies the condition?

As to the real roles of the players , even the team members don have too much of an idea......
Its more like we draw the map as we find our way to BLACKIS

I believe our Captain's post immediately after team was selected more or less details what's the intention of the DT and role each person can play whether in/outside the team. Adding on to it probably initiatives like the one currently in discussion i.e. discussing AIMCAT/SIMCAT/ProcMock papers or rather alternative solutions (as suggested by iamnutty which I feel is really great) is something.

Again this exactly is the intention of forming the team or role of each person in the team. Put together 15 brains or ideas instead of the whole lot of chennuys and find out what can/needs to be done so that each and everyone of us finds a seat in the hallowed portals of a premier B-school.

Adiyos. ATB. See ya on Sunday.

oh yes..... sunday ll be fine with me..... and guys how anout we discuss some simcat papers too if someone manages to get hold of it...... coz since we are at time we get used to the type of qns that they ask.... there lll be a differance solving simcat papers too.... we can try both on a frequent basis.......

Hi people!!

I m very sorry i got out of touch. I am in delhi on a new oven installaion project and remain on shop floor for 15 hours everyday

@Hari i have PMed u my mail address.....

Guys hope we all crack it this time with a bang!!!

Update:
I've emailed the invitation to view/edit the shared spreadsheet to some 10 people. For now, it has only contact details. Request the others to PM me their email address too, so that I can send the invitation. Also request everyone to update the spreadsheet!
Cheers,
Hari

Hi all,

First of all..Thanks to Naga..for considering my nomination..
and Hantan...who told me abt CDT..
i was not able to post ..due to some password issues..
well..henceforth will be an active contributor..

ps : hari , share the spread sheet link in ur post so that everyone can fill in their details rather than pm .. jus a suggestion :)

Hey Naga,
If I do that, the spreadsheet would be public..I thought of making it something shared only to our people here!! And I need to send an invitation to them, so need people's email ID's for that purpose..

dancingdaisies Says

.i hope ppl who r not part of the team can also join discussions & participate in meets right?

u can surely be the part of discussion not only chennai DT but also in other team :)

but strictly no spamming

As far as I know any chennuy can participate in the meets/discussions . There will probably be one this sunday... refer to Kapitaan Hari's post

small correction ..any puy can join in discussions in thread ! not necessarily only chennuys ! but as i said before , avoid spamming !

meet ofcourse - whomsoever is interested can come for it !

good luck!

ps : hari , share the spread sheet link in ur post so that everyone can fill in their details rather than pm .. jus a suggestion

This year there are no reserves / playing 11 ==> everyone is a player .
As to the real roles of the players , even the team members don have too much of an idea......
Its more like we draw the map as we find our way to BLACKIS

Hey guys..congrats on the team,...I don't understand the concept of playing 11 n reserves much here in PG though i do und in cricket anyways guess this is a forum where all chennai guys can get together n help each other out in prepping for CAT..i hope ppl who r not part of the team can also join discussions & participate in meets right?

People who are okay with Sunday evening please thank sachinrox's post above this..
And I request all u people to PM me ur email address, so that I can send u the invitation to view/edit the shared google spreadsheet..for now, it has only contact details, but we could eventually record our mocks scores in it as well..just to see whr we stand as individuals, and how the team is doing..as Naga mentioned in his post announcing the team, we should ALL make it to WIMWI/Joka

Sunday also fine by me.....

BTW for the AIMCAT 1010 discussion ...there are a few things to consider before the meet ::

who is gonna take lead in which section ?
- By what we decided in the meet , the person who has max percentile/score in that section should take lead...

who is gonna bring the Q paper ?

-One bring and all share / xerox for all and we all pay up ......or ne other solution :w00t:

Kaapitaan -- Wise Kaapitaan -- MinTor (Your Directions us pls )

PS :: I cant watch match even if i wanted to (no TV @ my place .. )

Dude even I like watching the matches. In fact it was craze for me. Immediately the day before my class 12 board exams for Maths was India Australia final for World cup 2003. Long back but just to give a hint how crazy I was. I studied sitting on the terrace, with FM radio to listen to scores and watching it in neighbor's TV!!! And again for world cup 2007 also something similar, but then not with tht much interest as India was out initially itself.

But then I realized there are some things more important, like for instance now we have our hands full with CAT. Match can always be watched as highlights, but yeah tht energy level will be lesser as u'll already know the result.

But again there is no highlights for CAT!!!
No offence meant, but dude if u're serious about CAT..CONCENTRATE. You have all the time in the world and lots of other matches, which will keep coming, to watch once u're in an IIM.

P.S: Cricket fanatics plz don't groan on this post too much!!

ajay ur absolutely correct... v cant compromise on CAT for cricket... but being an INDIA PAK match i couldn resist watchin itif thr s a meet on sat i ll definitely come.. but if at all sunday evenin s ok with everyone, v ll ve the meet on sunday??? jus a small request frm my side.. if its diffi..not a prob...

moreover match starts at 6pm in the evening .. even if we plan a meet , i am sure u can see atleast 60 overs of cricket..

Is Saturday evening okay for everyone? We could have a meet at IIT-CCD if it's okay with all u people..

I am mostly free on weekend and public holidays ....
I am free this weekend too... can join on sat/ sun .... just confirm the timings few days before.... so that I can schedule my office work...

its ok 4 me if the discussions dont involve aimcat 1009...cos i am writin it on sunday....

thagudu Says

ya this weekend any day will do for me!! and i say wat if we discuss 1010 instead?? also proc mock 5 cos most ppl giving that too!! those who don can be sent the pdf files! so these two papers can be discussed y wait fer 1009 to start discussions?? it has been some time since these 2 tests got over so each puy could just refresh the paper once before comin?? wat say chennuys??

I too have not written Aimcat 1009... I did write Aimcat 1010 yesterday...
so it would be fine if we discuss 1010.... I am fine with proc moc 5 , but i guess most people write aimcat... so it would be good if we start from aimcat...

Any Saturday and Sunday consider me OK by default (except maybe problem in timings) for a meet, unless and until I specifically come and say NO. Available 24x7 on those days and on the public holidays.

Just rearing to get back into the groove and get my performance curve going up again after 3 pathetic AIMCAT's where I failed to clear cut off in all 3 sections!! Started off with 1009 tho I won't clear VA yet again.

Anyways here's something which might be useful to all. Compilation of few major B-schools and gist of their application process. List is not yet complete as many are yet to come out with notifications.

Hello ppl...I know i'm super late in wishing the chennai makkal...but so what!!
heartiest congrats to everybody who has got selected....and all the very best too...
I can see that the chennai and kolkata DTs are the most active lot.Keep up the great work...but we at Mumbai will not be left behind

Congrats and good luck to all those who made it to the team! :)

Now let's get down to business!! Can someone explain Chinese remainder theorom with some examples?

before getting to chinese remainder theorem , let me explain whats the need for it?

problem:

find the smallest number when divided by 5 leaves 3 and when divided by 7 leaves 4

common approach

divisor of 5 + 3 - 3,8,13,18,23,28,33

divisor of 7 + 4 - 4,11,18,25,32

18 is common to both series .. so we have the answer...

same is the case with chinese remainder theorem

find the remainder of 3^1001 divided by 1001 ...

1001 - 7*11*13

so find the remainder when 3^1001 divided by 1001

3^1001 / 7 ----> 3^5/7 , remainder - 5

3^1001/11 ----> 3/7 ,remainder - 3

3^1001/13 ----> 3^5/13 , remainder - 9

so we get 7a + 5 = 11b + 3 = 13c+9

now what is word interpretation of the above statement ..

find the smallest number which when divided by 7 gives remainder 5 , when divided by 11 leaves remainder 3 and when divided by 13 leaves remainder 9?

first take any two condition , i always prefer big numbers

11b + 3 = 13c + 9

divisor of 13 + 9 = 9,22,35,48,61,74,87,100,113,126,139

divisor of 11 + 3 - 3,14,25,36,47,58,69,80,91,102,113

so smallest number is 113

whats the next number then ?

its of form LCM(11,13) + 113 = 143k + 113

so we have combined two conditions

so now our job is to compare this with third one

143k + 113 = 7a + 5

143k + 108 = 7a

140+ 3k + 105 + 3 = 7a

so 3k + 3 should give 0 remainder when divided by 7

so k = 6

final remainder is hence 143(6) + 113 = 971

this is all about chinese remainder theorem

to sum up , use this theorem only when denominator is factorisable to prime factors.


hope this helps....

will various topics from va di or/and qa be discussed in this thread?... if yes... the team members can charter out some strategy or schedule kinda stuff and we can ve qst s posted here which ll be solved on a daily basis ...that ll b very useful... thanks...:-P

ya this weekend any day will do for me!! and i say wat if we discuss 1010 instead?? also proc mock 5 cos most ppl giving that too!! those who don can be sent the pdf files! so these two papers can be discussed y wait fer 1009 to start discussions?? it has been some time since these 2 tests got over so each puy could just refresh the paper once before comin?? wat say chennuys??

somname Says

Can I also come and give gyaan now and then?

Aaah! The strategy coach is back!

Looking forward to your useful tips!

Congrats and good luck to all those who made it to the team! :)

Now let's get down to business!! Can someone explain Chinese remainder theorom with some examples?

its ok 4 me if the discussions dont involve aimcat 1009...cos i am writin it on sunday....

iamnutty Says

If the meet is gonna be scheduled this weekend could it be the sat evening or sunday evening??.....have booked aimcat on saturday morning ....

Is Saturday evening okay for everyone? We could have a meet at IIT-CCD if it's okay with all u people..

And our dear mentor, whr r u? We need ur inputs man!

i am very much there... carry on with ur ideas and ideas suggested by team members.. will be part of whatever team do

Further to the excel creation and contacts, we also have a few other activities lined up. As naga had mentioned B-school visit would be one. GLIM, IFMR, LIBA are the three for us here in Chennai. Later maybe after CAT, BIM and other institutes outside Chennai also may be looked at if everyone is interested.

I for my part was thinking a bit far fetched but only after D-Day. IIM A,I or IIFT!! Not official like by getting in touch with admissions co-ordinator and all. Guess they wont need tht kind of marketing after all!!! And the reason why I said these 3 is bcoz I've got friends there now, whom I can drop in and visit and at the same time get an idea of how things are. But after CAT it'll be some time when results are coming - Jan 23,24,25,26 is what I was thinking of, and results expected after Jan 22.

More of that later and coming back to what we have in Chennai. I believe GLIM has responded back with a date of October 10 as naga had informed in meet yesterday. Will be getting in touch with IFMR tomorrow and try for coming Saturday September 26.

Then of course as put by captain and others meets AT LEAST once every fortnight or as soon as AIMCAT results are out, would be on the cards. Then we could probably have some sessions to face exam jitters towards the fag end. I mean it wud sound stupid but as the D-day nears these goosebumps start creeping in. I definitely had last 3 years even without prep anything!! So we could have someone, say one of the OMPA members handle that.

All these ideas are prob long term, I mean 1-2 months. Immediate would be probably a self analysis as we are halfway through the mocks. So only with self analysis the meets would get more fruitful.

Btw if anyone has not noticed, no one from south in DT or UDT '09. Thats bad, very bad. :nono::nono: We got a point to prove to the selectors. So buck up and get rocking chennuys.

P.S: don't kill me when you see me next time for this boring lengthy write up!!

I shall soon create a google spreadsheet so that we can all enter our contact details..team bonding is important, wat say?
And we shall have chat conferences/meets after each AIMCAT ends, ie, when results are published. We could share strategies, tips and tricks etc.
I would actually like to have a team meet for starters. So tell me when all of u would be free.We can meet up and then talk abt what actually can be done so as to benefit everybody.

really nice to be a part of a BIG thing....... how about this friday or saturday evenin provided no one has any commitments the next day?

ya spreadsheet idea is great lets do tat!! great idea by our captain there. and ya a meet of all members at least once would be a great idea i think the sooner the better. since there are 15 ppl if its gonna be next week maybe we can inform everyone by midweek so that those out of town will know as well and will be able to make it. aimcat discussions also can take place simultaneously(gee this is wats multi tasking eh ). so a big to the plan from me.

Good question First of all, let us finalize the team. I suppose we've got acknowledgements from eceryone except Shreyans.
