I felt the paper was not very difficult… My answers match with yours for the first 6 questions. I didn’t know how to do 7,8,9. For 10 I got 61. 11&12 I got huge answers… Guess I over counted for 10,11,12.

    My last 3 seem incorrect but rest are going to be correct I’m sure.
    Any idea on how to do the last one?

I am in class 10th. My solutions - 1) 74 2) 67 3) 65 4) 3 5) 2 6) 4 7) 18 8) 15 9) 88 10) 61 11) 321 12) 2671 My 3rd question (7,8 and 9) is wrong most probably. I am not sure about the third part of the 4th question either.

Hey Guys,
My answers,although not accurate are
Q1 a)74 b)67 c)65
Q2 a)3 b)2 c)4
Q3 a)20 b)16 c)96
Q4 (My answers are all wrong,missed out on a couple of cases) but the first subpart is 61 for sure
The approximate cutoff should be around 30-40 for Class X and below, 40-50 for Class XI and around 50 for Class XII.
All the best to everyone :smiley:

1.) 74 2.) 67 3.) 65 4.) 3 5.) 2 6.) 4 7.) 20 8.) 16 9.) 96 10.) 61 11.) 321 12.) 2671 I got these answers.

1-- 73[Looks like I messed up on this one:P ]; 2-- 65 3-- 67 ; 4 – 3 ; 5-- 2 ; 6 – 2[Sure about this; I know it is different from your answers]; 7-- 16; 8-- 13; 9 – 35; 10-- 73; 11-- 481; 12-- 4321. Let’s wait and see what happens. I think the cut off will be 60 for class 12 and 5 points less for every subsequent class.

Hey guys! My answers were :

74, 67, 65

3, 2, 4

20, 16, 96

In my opinion, the paper was easier than the last year.

I expect the cutoff for class 12th to be about 60.
