NMTC 2K14 Is over...How well did you fare?

Hi Everyone! The 2014 NMTC (prelim) just concluded about an hour back in most indian cities. This competition known for its wacky and non-routine problems is quite akin to the Putnam Lowell competition as the median scores in this competition too are almost zero. (Because of the heavy negative marking). 2014 paper was a mix of happiness, sadness, shock and surprise to me. Actually it was a happy/joyous paper because it was quite an easy one ...(not too easy though)...sorrowful because I DIDN'T do my BEST.- I could have easily scored 20+ :(. Shocking because it contained some totally easy problems and surpising because despite it being easier than prev.papers, it was totally not-solvable in 2 hrs. ( unless you are truly a genius). Owing to my illness, My speed was badly reduced. I was able to attempt only 19 questions, though I could have easily notched up 3-4 more ones . Final score-19 (20 if +1 marks is given for Bonus) :'(

How well did you all fare? Please do post your scores! Do like and reshare so that it reaches a larger audience and we get to know their scores also!

PLS NOTE THAT I AM IN JUNIOR LEVEL AND SATVIK'S ANSWER KEY TOO IS APPLICABLE FOR THE SAME.

@Satvik Golechha See i have deleted the question because the problem is incorrect because \(\frac{AE}{E}=0.5\) not \(\frac{2}{3}\) if you fix the rest things.

@Mietantei Conan It is \(AE/EC\). Sorry for the typo.

Siddharth G - 3 years, 1 month ago

Log in to reply

Nope its 400 exactly. ANyway @Siddharth G - how much are you getting? What is the expected cut-off at your center? Where did you write it? What are your friends getting?

Krishna Ar - 3 years, 1 month ago

Log in to reply

@Krishna Ar Looks like 16.5. I gave it at my local FIITJEE centre(southdelhi). Don't know about their marks yet, probably tomorrow, due to my miserable paper, I came home without much discussion. Is the cutoff centre-wise?

For the 15th Q, the area of the larger triangle is 405 and the smaller one is 5.625. Subtracting, I got 399.375

Siddharth G - 3 years, 1 month ago

Log in to reply

@Siddharth G Well it's quite fine for qualifying.. Yes, its center-wise. Its a huge plus for those who gave it from their school like me, I just had to you know get above 10 and I got 10 marks more than needed. You must also keep in mind that only 10% would move on to the next round. So Cutoff would be decided by only how the people who wrote in the same center as you did. Well , for 15...you dont need to find areas of small/large and all that...only thin' you need to do is- Find ar(pllgm)=720. Then you get ar(tri.gdc)=640*0.5=320. Thus it is 720-320=400. I hope it was clear

Krishna Ar - 3 years, 1 month ago

Log in to reply

@Krishna Ar However, the competition in an institution like FIITJEE, is higher than a one in an average school. I think about 200 students would have given the test. Acc. to me, ar(gdc) = \(630*0.5\) =\(315\)

Siddharth G - 3 years, 1 month ago

Log in to reply

@Siddharth G Sid, if you use similarities, you will get it only as 640. Not 630. Donno how you got this..can you explain?

Krishna Ar - 3 years, 1 month ago

Log in to reply

@Krishna Ar Sorry, took the wrong ratio. Same reason why I got 399.375

Siddharth G - 3 years, 1 month ago

Log in to reply

@Siddharth G Ah...It's fine. Well , I think AMTI will accept this perhaps.

Krishna Ar - 3 years, 1 month ago

@Siddharth G One of my friends also got 399.375, but I got 400. Also, Brilliant will accept both, and so should the AMTI.

@Aditya Raut @Dinesh Chavan - How much are you guys scoring in INTER level ?

Krishna Ar - 3 years, 1 month ago

Log in to reply

I made some silly mistakes, otherwise I expected my score to be \(29/30\) ,but now it's gonna be less than that .....too less....


For example, I factorized \(27000001\) in half minute, using

\(300^3+1^3=(300+1)((300+1)^2-3\times 300 \times 1)\\=301\times (301^2-30^2 )= (301)(301+30)(301-30)=7\times 43\times 271\times 331\)

And after this, i wrote their sum as \(642\) in stead of \(652\)


At one place, I introduced \(\dfrac{1}{2}\) in heron's formula which is not there!!!


At one place, they asked double of that angle (ans being \(225^\circ\)), and I wrote the angle( \(112.5^\circ\) )


Once in my rough work, i saw my own \(6\) as \(9\), and wrote an answer that was greater than right one by 3.


One of them I left unattempted ,but later got it, just after giving the answer sheet back !


so sad right? LOL ! Few more mistakes like that, for which someone should slap me .... But nvm, that's a part and parcel of life :P

Aditya Raut - 3 years, 1 month ago

Log in to reply

Hmm... Seems like a tie! here are mine-
-- I found the answer for 16, went wrong with verification, and skipped the question.
-- In the AP formula, I divided by 2 twice!
-- Wrongly added four two digit numbers.
-- Took the wrong ratio in similarities.
-- \(37*2=39\)!
-- Multiplied both side by \(0\)

Log in to reply

@Aditya Raut Nope...In your case it was silly mistakes, in my case- I could have easily scored 5/6 marks more than what I'm getting (20)...so for me both are the same...everyone makes silly mistakes, I'm sure that you are selceted
