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: A
Explanation
1) TR120 → VX180
T → V (+2)
R → X (+6, +5)
120 × 1.5 = 180
2) BY246 → DD369
B → D (+2)
Y → D (+5)
246 × 1.5 = 369
3) CD122 → EI183
C → E (+2)
D → I (+5)
122 × 1.5 = 183
4) LW310 → NB465
L → N (+2)
W → B (+5)
310 × 1.5 = 465
Option 1 is different
