Equation I

Equation II

Neither I nor II

Both I and II

- Let's evaluate Equation I: 17 - 21 + 86 ÷ 2 × 13 = 387.

- If we swap × and -, the equation becomes 17 × 21 + 86 ÷ 2 - 13.

- Solving this gives: 357 + 43 - 13 = 387, which is correct.

- Now, consider Equation II: 10 + 63 - 12 × 259 ÷ 7 = 739.

- With × and - swapped, the equation is 10 × 63 + 12 - 259 ÷ 7.

- Solving it gives: 720 + 12 - 37 ? 739, making it incorrect.

- The correct answer is Option 2, Equation II.
