According to the question, after replacing the signs:
Option 1) - ÷ =
13∗2∗6∗25 ⇒ 13 - 2 ÷ 6 = 25
⇒ 13 - 2 ÷ 6 = 25
⇒ 13 - 0.33 = 25
⇒ 12.67 ≠ 25 (LHS ≠ RHS)
Option 2) - × =
13∗2∗6∗25 ⇒ 13 - 2 × 6 = 25
⇒ 13 - 2 × 6 = 25
⇒ 13 - 12 = 25
⇒ 1 ≠ 25 (LHS ≠ RHS)
Option 3) × + =
13∗2∗6∗25 ⇒ 13 × 2 + 6 = 25
⇒ 13 × 2 + 6 = 25
⇒ 26 + 6 = 25
⇒ 32 ≠ 25 (LHS ≠ RHS)
Option 4) + × =
13∗2∗6∗25 ⇒ 13 + 2 × 6 = 25
⇒ 13 + 2 × 6 = 25
⇒ 13 + 12 = 25
⇒ 25 = 25 (LHS = RHS)
Hence, "Option 4" is the correct answer.
