Which group of letters will come next in the given series?
PMK, MPK, MKP, KMP, ?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → KPM
All the groups use the same three letters P, M, K, so look at how the letters change places from one group to the next.
PMK to MPK: the first two letters change places
MPK to MKP: the last two letters change places
MKP to KMP: the first two letters change places
KMP to the next group: now the last two letters change places, so K M P becomes K P M
So the next group is KPM.
