In the following question, four letter-number pairs are given. The letter-number on the left side of (–) is related to the letter-number on the right side of (–) with some Logic/Rule/Relation. Three pairs are similar on the basis of same Logic/Rule/Relation. Select the odd one out 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: D
Explanation
1) AC → CH
A +2 → C
C +5 → H
332 × 1.5 = 498
2) BH → DM
B +2 → D
H +5 → M
440 × 1.5 = 660
3) LK → NP
L +2 → N
K +5 → P
556 × 1.5 = 834
In all three, the letter combinations are +2 and +5.
4) MZ → OF
M +2 → O
Z +6 → F
484 × 1.5 = 726
Option 4 is different.
