Three of the following letter-clusters are alike in some manner and hence form a group. Which letter-cluster does not belong to that group?
Answer & explanation
Correct answer: option 4
1 2 3 4 5 6 7 8 9 10 11 12 13
A B C D E F G H I J K L M
↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓
Z Y X W V U T S R Q P O N
26 25 24 23 22 21 20 19 18 17 16 15 14
THE LOGIC FOLLOWED HERE IS;
1) TVR,
T → (+2) → V
V → (-4) → R
2) DFB,
D → (+2) → F
F → (-4) → B
3) QSO,
Q → (+2) → S
S → (-4) → O
4) KGI,
K → (-4) → G
G → (+2) → I
Thus, KGI does not belong to that group.
