In the following question, select the odd letter-number cluster from the given alternatives.
(NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits. E.g.13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
Show answer & explanation
Correct answer: C
Explanation
1) ABDE12
ABDE
A → B (+1)
B → D (+2)
D → E (1)
A=1, B=2, D=4, E=5
Total = 1+2+4+5 = 12
2) PQST72
PQST
P → Q (+1)
Q → S (+2)
S → T (1)
P=16, Q=17, S=19, T=20
Total = 16+17+19+20 = 72
3) LMPQ58
L → M (+1)
M → P (+3)
P → Q (+1)
L=12, M=13, P=16, Q=17
Total = 12+13+16+17 = 58
4) EFHI28
EFHI
E → F (+1)
F → H (+2)
H → I (+1)
E=5, F=6, H=8, I=9
Total = 5+6+8+9 = 28
Correct Answer: LMPQ58 This pattern is different.
