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?

13

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:

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

20

I got 103 ( is this right ? )

21

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
