#12

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.


#13

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.


#15

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.


#16

Hey guys! My answers were :

74, 67, 65

3, 2, 4

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

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