In this type of questions, usually, 5 groups of letters are given. Four of them are similar to each other in some manner while one is different and this is to be chosen.

1)

In the following question choose the number-letter group which is different from others


A) DG2

B) EK5

C) JR6

D) PY8

E) RV3

Answer:

Option C

Explanation:

Putting A = 1, B = 2, .....,Z = 26,

We have : DG2 = G - (D + 2) = 7 - (4 + 2) = 1;

EK5 = K- (E + 5) = 11 - (5 + 5) = 1;

JR6 = R - (J +6) = 18 - (10 + 6) = 2;

PM8 = Y - (P + 8) = 29- (16 + 8) = 1;

RV3 = V - (R + 3) = 22- (18 + 3) = 1.
