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)
PK320 - OI604
In each pair, compare the two letters and the number on the left with those on the right.
First letter: it always moves one step back in the alphabet, S→R, P→O, E→D, T→S (a shift of −1).
Second letter: it always moves two steps back (cyclically), A→Y, K→I, B→Z, G→E (a shift of −2).
So the letter rule is the same for all four pairs; the distinguishing feature must be the number.
Check the number difference (right number − left number): 581 − 287 = 294, 525 − 231 = 294 and 704 − 410 = 294.
For the pair PK320 − OI604 the difference is 604 − 320 = 284, which is not 294.
Three pairs increase the number by 294 while PK320 − OI604 increases it by only 284, so this is the odd one out.
The odd one out is option 2, PK320 − OI604.
