Question
Four letter-clusters have been given, out of which three
are alike in some manner and one is different. Select the letter-cluster that is different.Solution
PSOR → P + 3 = S, S – 4 = O, O + 3 = R NQMP → N + 3 = Q, Q – 4 = M, M + 3 = P ZCYA → Z + 3 = C, C – 4 = Y, Y + 3 = B TWSV → T + 3 = W, W – 4 = S, S + 3 = V
