Correct Answer: Only II
Solution : Given: + and × l. 5 × 12 – 15 + 20 ÷ 30 = 7 II. 51 ÷ 17 × 9 + 10 – 8 = 85
After interchanging the symbols the equations are as follows – I. 5 × 12 – 15 + 20 ÷ 30 = 7 ⇒ 5 + 12 – 15 × 20 ÷ 30 = 7 ⇒ 5 + 12 – 15 × 0.67 = 7 ⇒ 5 + 12 – 10.05 = 7 ⇒ 17 – 10.05 = 7 ⇒ 6.95 ≠ 7 II. 51 ÷ 17 × 9 + 10 – 8 = 85 ⇒ 51 ÷ 17 + 9 × 10 – 8 = 85 ⇒ 3 + 9 × 10 – 8 = 85 ⇒ 3 + 90 – 8 = 85 ⇒ 93 – 8 = 85
Therefore, only the second equation satisfies the R.H.S. of the given equation. Hence, the fourth option is correct.
