So,
- Option - (1) : 2 : 9
2 × 3 + 3 = 9
6 + 3 = 9
9 = 9 (LHS = RHS)
- Option - (2) : 6 : 21
6 × 3 + 3 = 21
18 + 3 = 21
21 = 21 (LHS = RHS)
- Option - (3) : 10 : 33
10 × 3 + 3 = 33
30 + 3 = 33
33 = 33 (LHS = RHS)
- Option - (4) : 8 : 29
8 × 3 + 3 = 29
24 + 3 = 29
27 ≠ 29 (LHS ≠ RHS)
Hence, "Option - (4)" is the correct answer.
