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: B
Explanation
1. AC293 → VX503
A → V (−5)
C →
293 + 210 = 503
2. EG307 → ZA517
E → Z (−5)
G → A (−6)
307 + 210 = 517
3. FT511 → AO721
F → A (−5)
T → O(−5)
511 + 210 = 721
4. RB479 → MW689
R → M(−5)
B → W (−5)
479 + 210 = 689
Correct answer=EG307 → ZA517
