We have to put the mathematical signs to sequentially replace the * signs and balance the given equation.
Let's check each option one by one.
Option 1) × ÷ + -
Given: 16 * 3 * 2 * 11 * 9 = 22
⇒ 16 × 3 ÷ 2 + 11 - 9 = 22
⇒ 16 × 1.5 + 11 - 9 = 22
⇒ 24 + 11 - 9 = 22
⇒ 35 - 9 = 22
⇒ 26 ≠ 22
⇒ LHS ≠ RHS
Option 2) × ÷ − +
Given: 16 * 3 * 2 * 11 * 9 = 22
⇒ 16 × 3 ÷ 2 - 11 + 9 = 22
⇒ 16 × 1.5 - 11 + 9 = 22
⇒ 24 - 11 + 9 = 22
⇒ 33 - 11 = 22
⇒ 22 = 22
⇒ LHS = RHS
Option 3) ÷ × + +
Given: 16 * 3 * 2 * 11 * 9 = 22
⇒ 16 ÷ 3 × 2 + 11 + 9 = 22
⇒ 5.33 × 2 + 11 + 9 = 22
⇒ 10.6 + 11 + 9 = 22
⇒ 30.6 ≠ 22
⇒ LHS ≠ RHS
Option 4) ÷ + × ÷
Given: 16 * 3 * 2 * 11 * 9 = 22
⇒ 16 ÷ 3 + 2 × 11 ÷ 9 = 22
⇒ 5.33 + 2 × 1.22 = 22
⇒ 5.33 + 2.44 = 22
⇒ 7.77 ≠ 22
⇒ LHS ≠ RHS
Hence, the correct answer is "Option 2".
