Explanation:-
M + 2 = O,                                  Similarly,  C + 2 = E
I  – 2 = G,                                                             I  –  2  = G
K  +  2 = M,                                                        A  + 2 = C
E  – 2  = C,                                                           D – 2 = B

Hence, the answer is (d) EGCB.

Explanation:-
Palaeontology is related to Fossil  same as, Phrenology is related to Skull.

Hence, the answer is (b) Skull.

Explanation:-
The place value of A, F  & I = 1, 6 & 9
The square root of 169 = 13
The 13th place value of ‘M’ in alphabetic series.

Similarly,
The place value of A, B & A = 1, 2  & 1
The square root of 121 = 11
The 11th place value ‘K’ in alphabetic series.

Hence, the answer is (d) K.

4. Answer: (c) 20 : 105

Explanation:-
9 x 5 + 5  = 45 + 5
= 50

Same as,
20 x 5 + 5 = 100 + 5
= 105

Hence, the answer is (c) 20 : 105.

Explanation:-
22  = 2 + 2 = 4
The square of 4 = 4 x 4 = 16

Similarly,
24 = 2 + 4 = 6
The square of 6 =  6 x 6 = 36
Hence, the answer is (c) 24.
