1. Ans. c
Let the number of correct answer be ‘x’ number of wrong answers be ‘y’ and the number of questions not attempted be ‘z’
Thus, x + y + z = 50 …………….(i)
And x – y/3 z-6 = 32
The second equations we get,
7x – y = 242/7 + y
Since, x and y are both integers, y cannot be 1 or 2. The minimum value that y can have is 3.
2. Ans. c.
If we consider the third term to be ‘x’
The 15th term will be (x + 12d)
6th term will be (x + 3d)
11th term will be (x + 8d) and
13th term will be (x + 10d)
Thus, as per the given condition, 2x + 12d = 3x + 21d.
Or x + 9d = 0
x + 9d will be the 12th term.

2. solution
If first term is ‘a’ then
3rd term = a+2d
6th term = a+5d
11th term = a+10d
13th term = a+12d
15th term = a+14d
Given,
(a+2d)+(a+14d) = (a+5d)+(a+10d)+(a+12d)
a+11d = 0 ,ie the 12th term
