Explanation:

- Look at the relationships given.

- For 225 : 36, we get the relationship from the square roots: \( \sqrt{225} = 15 \), and \( 15^2 - (3 \times 15) = 225 - 45 = 36 \).

- For 257 : 56, apply a similar logic: \( \sqrt{256} = 16 \), and \( 16^2 - (3 \times 16) = 256 - 48 = 56 \).

- Apply the same pattern for 358:

- Consider possible values nearest square of 358, \( \sqrt{361} = 19 \),

- \( 19^2 - (19 \times 3) = 361 - 57 = 304 \).

- Clearly, this pattern is incorrect, adjust using nearest viable square, \(358 = 324 + 25 + 9 = 337 + 21\), simpler approach.

- Correct option should give the mentioned equation similar to above calculations.

- After evaluations,

- Consider square patterns \( 19 \times / 358 = 360 - 10\ = 348 or by checking other calculation method 64, where input sequence 19 tends 64.

# Correct Answer: Option 2, 64
