Vedic Math Tutorial Part -1

iimmaniac — Wed, 28 Jan 2009 14:16:14 +0000

Use the formula ALL FROM 9 AND THE LAST FROM 10 to perform instant subtractions.

For example 1000 – 357 = 643We simply take each figure in 357 from 9 and the last figure from 10.

So the answer is 1000 – 357 = 643And thats all there is to it!

This always works for subtractions from numbers consisting of a 1 followed by noughts: 100; 1000; 10,000 etc.
Similarly 10,000 – 1049 = 8951
For 1000 – 83, in which we have more zeros than figures in the numbers being subtracted, we simply suppose 83 is 083.So 1000 – 83 becomes 1000 – 083 = 917

Hope you find this post usefull, actually this is the time to learn these concepts so that you can get comfortable with these concepts at this point of time itself and when your mock starts, you can get ahead of lacks of people just by using these concepts. Watch out a few more tutorials to come..

AIMCAT 910 results

iimmaniac — Thu, 28 Aug 2008 05:27:00 +0000

I was searching a boulder to break my head, this was my reaction when i cheked my scores. I marked some questions incorectly !! i was unable to belive it as since CAT 2006 i hd taken evary possible care at least while marking. Anyways this taught me another aspect and i am sure i wont repeat this mistake again.
My performance was pathetic 87.33%ile, thanks to those 5 wrongly marked question, else i would at least have crossed 92 %ile. Anyways, there is no point in lamenting over spilt milk. This AIMCAT was real breazer for all. TIME has declared the cut offs at 10+, 11+, 14+ for QA, VA, DI respectively. I hope to get some time to analyze my performance at this AIMCAT. Sometimes work sucks every bit of your time.

However, whatever may be your score is, good or bad, dosent matter. Important point here is to check and analyze your mistakes and making sure not to repeat them in upcoming AIMCATs.
Never loose hope and never get demotivated. We still have 79 days to go and world can turn 79 times in this time. So pull your socks and fire with full throttle. I will update this blog again before the AIMCAT and after the AIMCAT.
Say it with me, I am improving, i wont loose, i will win..Lets win…This time now or never..

AIMCAT 0910 Analysis

iimmaniac — Mon, 25 Aug 2008 05:15:00 +0000

Yet another AIMCAT, well, before i get lost in the work let me put some analysis of the latest AIMCAT 0910.
PS: this is totally my own perception about the test

QA: This section was not that tough but selection of question was the major role palyer in conquering this section. Some question like 1,8,17,20,21,22,31,32,34,35,46,48 should have attempted. I will put the detailed analysis once i finish the analysis. The cut offs are predicted towards 14-16 for QA section.

VA: English was real treat for VA lovers this time. Some passages were real easy ans so were the parajumbles. One should have left the Summary question as those were time consuming. The cut off are around 15-16 for this section.

DI: Ahh, was the fantastic section this time. Last 10 question were all sitters and should have attmepted in not more than 15 mins. Question sets like the “Bus transport”, “No of erasers in the office”, “Cold Drink brands and companies” were really easy and one should have attempted them with at least 95% accuracy. (For a change I did this time, he he)

Over all the paper was feel – good factor for all those who are struggling in past few AIMCATs. But the task is not over yet. You should tear out the paper with the analysis. Let me know your thoughts and concerns on this AIMCAT. Lets share..

AIMCAT 0917 analysis

iimmaniac — Mon, 07 Jul 2008 09:53:00 +0000

Another one shot of AIMCAT and the very firts AIMCAT with sub-sections of this season. The test was moreover on the platform of CAT 2005 which had the sub-sections and it has been around 3 years CAT have not used this type, so it was a good experience for everyone of us who is aiming to bell the CAT this year.
Well, Starting with the analysis, as TIME says test was easier than that of CAT 2007 paper.
VA:
With only one easy question, numbered 15, this section was more over of medium level of difficulty. However many and even i myself are victim of this sub-section thing. Section – A was given weightage of only 20% and there were 10 questions. One must have thought to solve some question of this section and then go to Sec- B but as i said, at least i was accustomed to give equal time to every section, a messed up was obvious. But im ust say it is good to do all mistakes in Mocks.
Question wiht mediaum difficulty were 1,3,5,6,8,11,16,17,18,19,2,22,23,24,26and 29 and resr were difficult. Cut offs are expected around 30 marks

QA:
I must say i am doing every possible misyke in AIMCATs in QA section only. Anyways, this section had few easy question, numbered 31,34,36,35. Cut off of this section is expected around 32 marks.

DI:
Some sets from section A were really easy. The set of players playing diff. games and living in diff cities was really simple. Another set on Credit cards was very easy (I am fool to solve it wrong )
Section – B , the first set was quite lengthy, but i must say the secod question and the last from this set were really easy. Rest sets were more over of the difficult level.
Cut offs are expected around 28 makrs
Overall cut offs for 1 IIM call are around 110 +

Regarding my scores?? i am analyzing the test right now, i will update as soon as i finish analyzing..

AIMCAT 0918 Results Out !!

iimmaniac — Thu, 26 Jun 2008 04:43:00 +0000

AIMCAT 0918 results are out now, first of all soory for posting after so many days as had benn busy in projects. Well, this AIMCAT was a real opprtunity to test where you preparations are heading. Questions were easy, YES easy !! even though it wont appear easy at first hand.
In the QA section, there were minimum 8 question those one could have solved if one’s concentration during the test was highest. The cut off for this section is at 21 marks (5 questions). Few question i want to discuss out here.
I dont remember the question number so please pardon me for that.
There was a question i think question 49, was the easiest of all..IF you are able to draw the figure properly, Bang !! 4 marks and figure was not that tough to draw. The clue in this question was the use of “Alternate segment theorem”.

With the use of this answer was there in your hands in less than 2 minutes. I missed this one because of oversight. This i have been telling to my self to read each and every question and i even decide that i will not let any question go out of my eye sight but some how this keeps happen. Lets see, i am trying to improve on this.

Secondly, there was a question 28, that talks about number of people are games that they play. simple writing down the equation in terms of veriables a,b,c,d…. would have fetched you 4 marks straight away. No skills were required to solve this one. I solved this one wrong !!

Now there was a question number 34 i think, please cross chekc the question number.
It talks about a+b+c+d = 13 and we were asked to find minimum value of sum of cubes of a,b,c,d given that all are positive integers.
Man, this was the question for which i am breaking my head that i never tried to solve it.
Now tell me what will be the minimum value of sum of a,b,c,d if a+b+c+d = 13???
Obviously when a=b=c=d = 13/4 isn’t it??
But as all are integers, we can take this value for a,b,c,d, now lets take nearest integer value of this fraction and this comes out as 3 !!
Now try to consider value of variables as 3, but a+b+c+d = 3+3+3+3 => 12 !! so we need to increase one of the value by 1 so the sum becomes 3+3+3+4 = 13 !!
Now use these values and determine the sum of cubes of these values and this come out as 145 !!
4 marks more. I think we are at 12 marks by now..

Now this i remember clearly, question number 32, that asked you to clculate the ratio of sides and ration of other sides was given as 4:3
I am not saying this was poor question but belive me if you are good at similarity of triangles, you would have fetched 4 marks for sure…

Now comes again one of the most simple question, 43..
It talks about dishonest sugur marchant and his gain on trading, He manages to get 20% more sugure initially that means if he is intended to get 100 Kg of sugure, he manages 120 Kg. And suppose the price of sugure is 1 Rs so he initially invested 100Rs. Now 30% of sugur actually delivered is added to get original quantity i.e. 30% of 120 => 36 which gets you to 156, and it was stated that he charges 10% of initial claiming his transportation cost so 10% of 100 => 10 so adding this we get 156 + 10 = 166 so total gain is 66% !! More 4 marks..

Now i wanna discuss the question number 47, was most easy and was solvable in not more than 1 min. It talks about points that lie on and between the trinagle with co-ordinate (0,0) (0,5)(5,0).
It ask you to find number of integer points on this figure.
Even if you draw the figure and mark points manually, it will land you to 10 Points, Try it. Draw the figure and have a look your self.
By now we are up to 20 marks i.e. 1 mark short of cutoff and %tile near to 93-94 !!

Well, there are some more questions but i wont discuss them out here. These were the question one could have managed to solve in less than 15 min at max and cut off was clear. I missed this althoguh claiming i was not fresh enough to write the test but i understand CAT wont let me give any excuse and i have to crack it any how…
Hope i wont repeate these silly mistakes in the coming AIMCAT !! All the best and congrats for the people who scored well on this test.

Ameya

AIMCAT 10919 results out !!

iimmaniac — Thu, 12 Jun 2008 04:46:00 +0000

Finally AIMCAT 919 results are out and availabler on TIME’s website. My score was slightly lesser compared to what i had calculated. I ended up in scoring 93.84%ile on DI with 90.91 % accuracy which is the only point for my being elated. Then Verbal was on 96.2%ile wiht poor 70% accuracy but still i am happy that i have cleared the cut offs. Then comes the Monster QA section, it is proving my calling it a nemesis. Well, QA was poor 70%tile so i missed the bus here because of QA again. Overall i scored 93.34 %ile.

People can assess their performance now as AIMCATs are really getting into the business now. But as i said earlier, after analyzing QA section , i came to know my mistakes. There were 3 questions which one could have solved in 10 mins. Only thing required was keen observation. Well, i am keen observe it in upcoming AIMCATs as the next AIMCAT is scheduled on 22nd June.
People can access their scores from the following link, or you can post your TIME Id, if it is in top 5000 students i will post the score and percentile here itself.

Hope it helps.

AIMCAT 0919 DI Section analysis.

iimmaniac — Tue, 10 Jun 2008 13:51:00 +0000

If anybody has analysed AIMCAT 919 properly then it could be observed that DI was a scoring section. I understand there were questions that were tough, but if you look closely then in the first 5 questions of DI section, 1st, 2nd and the last one were easy and anyone could have managed to solve them will 100% accuracy in less than 5 mins, no calculation was involved.Then question 10th was just based on observation. Then if you consider the questions from 11-15, 11th,12th and 13th were doable but needed trial and error approach. Then look ofr questions from 16th – 20th out of these high calculation based question, 16th was easiest and had just concept of percentages. and if you are avg. at observing percentages then you could have solved 18th also.I am not saying that i have solved all of these qestions, but few of them. I have scored mere 29 in DI but after this analysis i came to know that had i alloted 5-8 mins more to DI i would have scored more than 40 !!

Well, this was the analysis that i did for myself. I will suggest each one of you to follow the same approach for analysing AIMCATs.
I will post the QA analysis after sometime. Mean while hope these contents helps.

Ameya
