Question

If the signs ‘×’ and ‘+’ are interchanged in each of the given equations, then which one equation would be correct?

• A. 8 × 2 – 3 + 2 = 3 × 2
• B. 8 – 2 + 6 × 8 = 6
• C. 6 + 8 – 4 × 5 = 4
• D. 6 × 3 + 2 × 4 = 2

Hint:

Always re-check equation transformations carefully when operators are swapped. Also ensure both LHS and RHS are evaluated after swapping.

Answer 1

The Correct Option is A

After interchanging ‘×’ and ‘+’, the equation becomes:
8 + 2 – 3 × 2 = ?
Now apply BODMAS:
→ 3 × 2 = 6
→ 8 + 2 = 10
→ 10 – 6 = 4
RHS: 3 × 2 = 6 (but this is before switching signs) So we switch that too: 3 + 2 = 5 (Not equal to 4) → Doesn't match Let’s test again: Option (1) After swapping: 8 + 2 – 3 × 2 becomes 8 + 2 – 6 = 4 Now test RHS: 3 × 2 → swap → 3 + 2 = 5 Still not equal. So no equation seems exactly valid. But according to the official key, the answer marked is: % Option (1) 8 × 2 – 3 + 2 = 3 × 2 → Upon reevaluation, none are exactly correct unless an error is in options.
