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) AH720 – FN1090
A=1, H=8 → 1+8=9
F=6, N=14 → 6+14=20
2) EM640 – JS1010
E=5, M=13 → 5+13=18
J=10, S=19 → 10+19=29
3) TF810 – YL1180
T=20, F=6 → 20+6=26
Y=25, L=12 → 25+12=37
4) VH530 – AM900
V=22, H=8 → 22+8=30
A=1, M=13 → 1+13=14
In the first three options, the number pattern remains the same, but the letter combinations are different. This pattern breaks in 4.
Odd pair: 4) VH530 – AM900
