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 !!

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?
