@lokesh2002 I also got the same answers for Q1, 2, 3 (3b was 520). For fourth, I think the answer for a is 72. I don’t know about 4b and 4c.

3

Can anyone give full question 4 statement

4

In your opinion what will be the cutoff this year?

5

The answer for 4a is 144.

6

is there some specific reason for my answers in ques 1 to be less by 6 than the most accepted answers in each case.
my answers are
1=>63
2=>99
3=>127

7

Any guesses on what the cut off is going to be for 11th? It was 40 last year IIRC and IMO, this year the test was way harder so 35-40?

8

My answers:
1] 70,
2] 102,
3] 117,
4] 7 ,
5] 7,
6] 11,
unfortunately, I got further answers are wrong, the answers were too small to compare with!

9

What would the cutoffs be for 9th grade?

10

could somebody please send me the link to the ICO whatsapp group?
thanks in advance :slight_smile:

@kayak
I guess your answer is wrong
You are not taking care of the fact that there should be one and only -1 product in row and column each
If you fill other spaces arbitrarily then there are chances that there are more rows and columns with -1 as their products.
