Four letter clusters have been given, out of which three are alike in some manner, while one is different. Choose the odd one.
- AGAT
- BDAT
- CEAV
- DWAD
Solution & Step-by-step Explanation
Let's analyze the relationship between the first and last letters of each option using their positional values in the English alphabet:
GAT: G=7, T=20. Sum of positions = 7+20=27 (Opposite pairs).
DAT: D=4, T=20. Sum of positions = 4+20=24.
EAV: E=5, V=22. Sum of positions = 5+22=27 (Opposite pairs).
WAD: W=23, D=4. Sum of positions = 23+4=27 (Opposite pairs).
In all options except DAT, the first and last letters are opposite pairs of the alphabet (their sum is 27).
