Letter Series Analogy Question

In this verbal reasoning problem, we need to find the pattern between the first two sets of letters and apply it to the third set.

Let's examine the first relationship: I-R-O-T-M maps to R-T-L-W-N. We should look at their positions in the alphabet or their alphabetical opposites.

The letters I and R are opposites in the alphabet. I is ninth from the start, and R is ninth from the end. Similarly, O and L are opposites.

Wait, let's re-examine that. R is the opposite of I. T is two steps after R. L is the opposite of O. W is three steps after T. N is the opposite of M. This looks like a mixed pattern.

The pattern alternates between taking the alphabetical opposite and adding sequential values. Let's test this on the second group: K-P-S-R-T.

First, take the opposite of K. K is the eleventh letter. Twenty-seven minus eleven is sixteen, which is P.
