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.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. DOU
Logic: Subtract the positional value of the third letter from the first letter to get the second letter.
ODS = O(15) D(4) S(19) = 19-15 = 4
AHI = A(1) H(8) I(9) = 9-1 = 8
GNU = G(7) N(14) U(21) = 21-7 = 14
DOU = D(4) O(15) U(21) = 21-4 = 17 (not follow)
So, DOU is unlike this.
Hence, the correct answer is DOU.
