Three of the following four letter-clusters are alike in a certain way and one is different. Pick the odd one out.
A. GESO
B. MZLY
C. IVHU
D. KXJW
Sol:
1) G + E + S + O = 7 + 5 + 19 + 15 = 46 which is not a multiple of 4.
2) M + Z + L + Y = 13 + 26 + 12 + 25 = 76 = 4 × 19
3) I + V + H + U = 9 + 22 + 8 + 21 = 60 = 4 × 15
4) K + X + J + W = 11 + 24 + 10 + 23 = 68 = 4 × 17
All the other letter clusters are multiple of 4 except for GESO (46) hence the correct answer. Hence, ‘GESO’ is the correct answer.
