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)
EW22 − DV676
In this letter-number analogy the letters and the number can carry different rules, so we look for the arithmetic link that produces the right-hand number from the left-hand number.
Testing the numbers reveals the rule: take the given number, add 2, and square the result. That is, right number \(= (\text{number} + 2)^2\).
Check AS16: \((16 + 2)^2 = 18^2 = 324\), matching HZ324 — rule satisfied.
Check PI18: \((18 + 2)^2 = 20^2 = 400\), matching RK400 — rule satisfied.
Check UH20: \((20 + 2)^2 = 22^2 = 484\), matching SF484 — rule satisfied.
Now check EW22: the rule predicts \((22 + 2)^2 = 24^2 = 576\), but the pair shows 676, which is actually \(26^2\). So this number does not follow the (number + 2) squared pattern.
Hence the odd one out is EW22 − DV676.
