Sorry I don't think so. As far as I can remember, answers were B (for 3) and C (for 4)
3. Sum of 50 positive odd integers: 2500
A. 2000 B. 2500 C. 2550 D. None of these (I think)
4. Sum of 50 positive even integers: 2550
A. 2000 B. 2500 C. 2550 D. None of these (I think)

MATHS:
1. Product of complex number and its conjugates: always real number
2. Question about matrix where value is zero if a=b and 1 if a is not equal to b. Answer is Identity Matrix
3. Sum of 50 positive odd integers: 2500
4. Sum of 50 positive even integers: 2550
5. No of diagonals of 8 sided figures: 20
6. Triangle having sides a=96, b=70 and c=50. Largest angel formed by which side
A. a. B. b. C. c
7. Work done by Force F(2i+j+k) and distance of P(0,0,0) and Q(1,2,2).
8. Momentum of Force F(2i+2j+2k) And Point Q(1,2,2)
9. One question about find projection of one vector upon 2nd vector (Note:vectors were given)
10. A man buy 6 coats, 4 trousers and 3 shirts. In how many way he can wear them? 72
11. A box have 9 white balls, 7 red balls and 5 blue balls. What is probability of having no white ball? 13/20
12. A box contains 9 red balls and 2 white balls. Probability of choosing any ball: 1
13. A LMN triangle having points L(0,0,0), M(1,1,1) and N(2,2,2).what is centroid
A. 0,0,0. B. 1,1,1. C. 2,2,2
14. Real part of inverse multiplication of 4+6j
a. 3/25
b. 4/25 (I think this is the answer)
c. -3/25
15. Sum of infinite series 1+1/3+1/9+1/27.

Corrections are welcome. Also was anyone able to solve the questions 6, 7, 8, 9, 13, 15?

6- Largest angle is opposite to largest side.
7- work done is F.d=6
8-Moment= rxF=3j-3k
9-Projection's correct answer was None of these'
13-Centroid was (1,1,1)
15- Sum of infinite series was 3
14- Answer of Inverse was 4/52

It's hard to guess at this point, because we haven't seen the Batch 2 and 3 papers yet. For Batch 1 Maths will be a deciding factor. If there are people with 10 out of 16 marks in Maths portion only, then cut-off will be 87-88.

If I'm being optimistic, cut-off will be 83-84, and I'll be surprised if it goes below that level.

Alright. What is your expected score?

The series was 2+(2/3)+(2/9)+(2/27)+.... upto infinity
Solution: 2[1+(1/3)+(1/9)+(1/27)+...]
=2[1/(1-(1/3))]
=2[1/(2/3)]
=2[3/2]
=3
