Logic :

  • (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".
