  • C. ÷ and –
  • D. – and ×
Correct Answer: Option B - Equation ‘9 × 182 + 14 ÷ 67 – 33 = 151’ From option (b) interchanging the signs– ⇒ 9 × 182 ÷ 14 + 67 – 33 = 151 ⇒ 9 × 13 + 67 – 33 = 151 ⇒ 117 + 67 – 33 = 151 ⇒ 184 – 33 = 151 ⇒ 151 = 151 L.H.S = R.H.S
B. Equation ‘9 × 182 + 14 ÷ 67 – 33 = 151’ From option (b) interchanging the signs– ⇒ 9 × 182 ÷ 14 + 67 – 33 = 151 ⇒ 9 × 13 + 67 – 33 = 151 ⇒ 117 + 67 – 33 = 151 ⇒ 184 – 33 = 151 ⇒ 151 = 151 L.H.S = R.H.S
