According to the question, after replacing the signs:
Option 1) × ÷ × +
16 * 3 * 2 = 110 * 2 * 5 ⇒ 16 × 3 ÷ 2 = 110 × 2 + 5
⇒ 16 × 3 ÷ 2 = 110 × 2 + 5
⇒ 16 × 1.5 = 220 + 5
⇒ 24 ≠ 225 (LHS ≠ RHS)
Option 2) × + ÷ -
16 * 3 * 2 = 110 * 2 * 5 ⇒ 16 × 3 + 2 = 110 ÷ 2 - 5
⇒ 16 × 3 + 2 = 110 ÷ 2 - 5
⇒ 48 + 2 = 55 - 5
⇒ 50 = 50 (LHS = RHS)
Option 3) × - + ×
16 * 3 * 2 = 110 * 2 * 5 ⇒ 16 × 3 - 2 = 110 + 2 × 5
⇒ 16 × 3 - 2 = 110 + 2 × 5
⇒ 48 - 2 = 110 + 10
⇒ 46 ≠ 120 (LHS ≠ RHS)
Option 4) ÷ × + ×
16 * 3 * 2 = 110 * 2 * 5 ⇒ 16 ÷ 3 × 2 = 110 + 2 × 5
⇒ 16 ÷ 3 × 2 = 110 + 2 × 5
⇒ 5.33 × 2 = 110 + 10
⇒ 10.66 ≠ 120 (LHS ≠ RHS)
Hence, "Option 2" is the correct answer.
