- (1st number + 1)= (Square of 3rd number)
- (3rd number × 5) = 2nd number
So,
- Option - (1) : 24 ∶ 25 ∶ 5
24 + 1 = \((5)^2\)
25 = 25 (LHS = RHS)
And,
5 × 5 = 25
25 = 25 (LHS = RHS)
- Option - (2) : 35 ∶ 36 ∶ 6
35 + 1 = \((6)^2\)
36 = 36 (LHS = RHS)
And,
6 × 5 = 36
30 ≠ 36 (LHS ≠ RHS)
- Option - (3) : 8 ∶ 15 ∶ 3
8 + 1 = \((3)^2\)
9 = 9 (LHS = RHS)
And,
3 × 5 = 15
15 = 15 (LHS = RHS)
- Option - (4) : 3 ∶ 10 ∶ 2
3 + 1 = \((2)^2\)
4 = 4 (LHS = RHS)
And,
2 × 5 = 10
10 = 10 (LHS = RHS)
Hence, the correct answer is "35 ∶ 36 ∶ 6".
