1. (c) HJJY

Explanation:-
C + 1 = D,   D + 1 = E  &   P + 2 = R,
D + 1 = E,    E + 1= F   &  R + 2 = T,
E + 1 = F,    F + 1= G  &   T + 2=  V,
F + 1  = G,   G + 1 = H  &  V + 2 = X,

Same as,
G + 1 = H,  H + 1 = J  & X + 2 = Z

Hence, the correct answer is option (c) HJJY.

2. (c) 2

Explanation:-
1 x 2 /8 = 1/4,      1 x 2 /4 = 1/2,    1 x 2 /2 = 1,

Same as,
1 x 2 = 2

Hence, the correct answer is option (c) 2.

3. (b) 41

Explanation:-
11 + 1^2  = 11 + 1
= 12,
12 + 2^2 = 12 + 4
= 16,
16 + 3^3 = 16 + 9
= 25,

Same as,
25 + 4^2 = 25 + 16
= 41

Hence, the correct answer is option (b) 41.

4. (d) 93.

Explanation:-
3 + 6 = 3 + 6
= 9,
9 + 2 x 6  = 9 + 12
= 21,
21 + 2 x 12 = 21 + 24
= 44,

Same as,
44 + 2 x 24 = 44 + 48
= 93.

Hence, the correct answer is option (d) 93.
