Given: 8 * 7 * 3 * 29480÷0.3×5+500190+9×27÷1.6=2 480÷0.3×5+500190+9×27÷1.6=2 480÷0.3×5+500190+9×27÷1.6=2 480÷0.3×5+500190+9×27÷1.6=2 480÷0.3×5+500190+9×27÷1.6=2

According to the question, after replacing the signs:

Option 1) × + =

8 * 7 * 3 * 29 ⇒ 8 × 7 + 3 = 29

⇒ × 7 + 3 = 29

56 + 3 = 29

⇒ 59  29 (LHS ≠ RHS)

Option  2) ÷ × =

8 * 7 * 3 * 29 ⇒ 8 ÷ 7 × 3 = 29

⇒ ÷ 7 × 3 = 29

1.14 × 3 = 29

⇒ 3.42  29 (LHS ≠ RHS)

Option  3) + × =

8 * 7 * 3 * 29 ⇒ 8 + 7 × 3 = 29

⇒ 8 + × 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.
