Any buddy, please provide me the JEST theoretical computer science previous year paper………

This is the JEST theoretical computer science previous year paper:

(a) Let a and b be positive integers such that a>b and a2 − b2 is a prime number.
Then a2 b2 is equal to
(A) a b
(B) a + b
(C) a b
(D) none of the above
(b) When is the following statement true? (A ∪ B) ∩ C = A ∩ C
(A) If ¯A ∩ B ∩ C = φ
(B) If A ∩ B ∩ C = φ
(C) always
(D) never
(c) If a fair die (with 6 faces) is cast twice, what is the probability that the two
numbers obtained differ by 2?
(A) 1/12
(B) 1/6
(C) 2/9
(D) 1/2
(d) T(n) = T(n/2) + 2; T(1) = 1
When n is a power of 2, the correct expression for T(n) is:
(A) 2(log n + 1)
(B) 2 log n
(C) log n + 1
(D) 2 log n + 1
