I thought that the paper was quite easy. Please do share your answers and the expected cutoff.

Is 60 safe for 11th?

Last question’s answer for the last part was 104

  1. I got 104

Oh, okay, I must have made a silly mistake :frowning:

Will 70 marks be enough for clearing ZIO (Grade 11)?

Also, when is the result usually announced?

I made the same mistake, even mine was 105 but as agreed by most of the people its 104. Also I realised my mistake later :stuck_out_tongue:

    I think my last answer is wrong so can someone provide the solution for last question.
    By the way I am in class 10 so what will be the expected cut off ? and will I qualify for INOI

Please explain how you got it?

Could you please explain how you got 104?

floor(2*sqrt(”the number given”) -1)

answer for 12th is 104. I checked with a brute force code after reaching home.

I got 103 ( is this right ? )

run this python code

for n in [2808]:
    aa=set()
    for i in range(1,n+1):
        aa.add(n//i)
    print(len(aa))

it gives 104
