Given equation I. 7 – 6 + 2 ÷ 1 × 9 = 2
Now, if '× and +' are interchanged, then:
⇒ 7 – 6 × 2 ÷ 1 + 9 = 2
⇒ 7 – 6 × 2 + 9 = 2
⇒ 7 – 12 + 9 = 2
⇒ 16 - 12 = 2
⇒ 4 ≠ 2
LHS ≠ RHS.
Given equation II: 16 + 4 – 9 × 1 ÷ 3 = 60
Now, if '× and +' are interchanged, then:
⇒ 16 × 4 – 9 + 1 ÷ 3 = 60
⇒ 16 × 4 – 9 + 0.33 = 60
⇒ 64 – 9 + 0.33 = 60
⇒ 64.33 - 9 = 60
⇒ 55.33 ≠ 60
LHS ≠ RHS.
Here, Both Equation I and II are the incorrect after interchanging the given symbol.
Hence, the correct answer is "Option 1".
