Four letter-clusters have been given, out of which three are alike in some way, and one is mismatched. Choose the mismatched letter-cluster.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. HLNQU.
Logic: The letters in each set of elements have been succeeded by three places.
1. HLNQU → H + 3 = K (not L), K + 3 = N, N + 3 = Q, Q + 3 = T (not U)
2. BEHKN → B + 3 = E, E + 3 = H, H + 3 = K, K + 3 = N
3. UXADG → U + 3 = X, X + 3 = A, A + 3 = D, D + 3 = G
4. CFILO → C + 3 = F, F + 3 = I, I + 3 = L, L + 3 = O
