Post your answers if they are different


All of my answers match with yours except Q.4
I have ‘3’ as my answer to that qn.
Can somebody post Q4 as I don’t remember what the qn was !!

Even I got same answers

I believe they are all correct

Yo man ! Exact same answers . How much are you guys expecting the cutoff to be ?

It was that rectangular sheet folding question for n=9 . My answer is 4 .

I think the cutoff would be ~60. Not sure, a lot many are getting full.


Okk . Nice approximation. I wish I get 80 . Do you know when IARCS is gonna release their answer key and results ?

All were same except the last one… I believe it should be 103 as 52 is being counted twice

Nope…the pair is (52,54). So you aren’t counting 52 twice…
And regarding Q4…I realised my mistake after discussing with a friend…the answer is indeed 4.

Is there a chance to qualify with 70 and when is the official key coming?

9th one I am getting 76. 12th one I’m getting 103 .Please check it again.I’ll also check

12th m too getting 103 but 9th is 77, 38+39 you must have given both X and y 38 to minimise the difference but doing so k isn’t satisfied

Since I completed the paper 1 hour prior I calculated using the calculator there were 2 52 one 52.02 or something and another 52.96 or something.

What’s the answer according to you ? 103 104 or 105 ?

i also got 103

But I got to know my mistake and the correct answer is 104

Is 52 counted twice?

there’s already one thread on the same topic created yesterday.
might be you missed seeing it.refrain from creating multiple threads in the future

Even i got 103
