According to the question, after replacing the signs:
Option 1) × + =
8 * 7 * 3 * 29 ⇒ 8 × 7 + 3 = 29
⇒ 8 × 7 + 3 = 29
⇒ 56 + 3 = 29
⇒ 59 ≠ 29 (LHS ≠ RHS)
Option 2) ÷ × =
8 * 7 * 3 * 29 ⇒ 8 ÷ 7 × 3 = 29
⇒ 8 ÷ 7 × 3 = 29
⇒ 1.14 × 3 = 29
⇒ 3.42 ≠ 29 (LHS ≠ RHS)
Option 3) + × =
8 * 7 * 3 * 29 ⇒ 8 + 7 × 3 = 29
⇒ 8 + 7 × 3 = 29
⇒ 8 + 21 = 29
⇒ 29 = 29 (LHS = RHS)
Option 4) - × =
8 * 7 * 3 * 29 ⇒ 8 - 7 × 3 = 29
⇒ 8 - 7 × 3 = 29
⇒ 8 - 21 = 29
⇒ -13 ≠ 29 (LHS ≠ RHS)
Hence, "Option 3" is the correct answer.
