Given: 1541050480÷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 interchanging the signs:

Option 1) ×, +, =

1541050 ⇒ 15 × 4 + 10 = 50

⇒ 15 × 410 = 50

60 + 1050

⇒ 70  50 (LHS ≠ RHS)

Option  2) -, ×, =

1541050 ⇒ 15 - 4 × 10 = 50

⇒ 15 - × 1050

⇒ 15 - 4050

⇒ -25  50 (LHS ≠ RHS)

Option  3) ×, -, =

1541050 ⇒ 15 × 4 - 10 = 50

⇒ 15 × 410 = 50

60 - 1050

⇒ 50 = 50 (LHS RHS)

Option  4) +, ×, =

1541050 ⇒ 15 + 4 × 10 = 50

⇒ 15 + × 1050

⇒ 15 + 4050

⇒ 55  50 (LHS ≠ RHS)

Hence, "Option 3" is the correct answer.
