If ‘+’ = ‘÷’, ‘−’ = ‘×’, ‘×’ = ‘+’, ‘÷’ = ‘−’, which equation is incorrect?

1. 12 + 4 - 2 = 5
2. 10 × 3 ÷ 5 = 8
3. 8 ÷ 4 + 2 = 6
4. 6 - 2 × 3 = 15

Correct answer: 12 + 4 - 2 = 5

After substitution, option A becomes 12 ÷ 4 × 2 = 6, not 5. The other equations are correct when the symbols are replaced as given.
