If  ‘+’ = ‘÷’,  ‘×’ = ‘+’,  ‘–’ = ‘×’,  ‘÷’ = ‘–’ . Then, which one of the following four equation would be correct ?

15 + 5 – 2 ÷ 6 × 6 = 6

Option (a)

15 ÷ 5 × 2 - 6 + 3

15 - 5 + 2 × 6 ÷ 3

15 - 7 × 2

15 - 14

1 ≠ 30

Option (b)

15 × 5 + 2 - 6 ÷ 3

15 + 5 ÷ 2 × 6 - 3

15 + \(\frac{5}{2}\) × 6 - 3

15 + 15 - 3

27 ≠ 60

Option (c)

15 + 5 - 2 ÷ 6 × 6

15 ÷ 5 × 2 - 6 + 6

3 × 2 - 6 + 6

6 - 6 + 6

6 = 6

Option (d)

15 - 5+ 2 × 6 ÷ 3

15 × 5 ÷ 2 + 6 - 3

15 × \(\frac{5}{2}\) + 6 - 3

15 × 2.5 + 6 - 3

37.5 + 6 - 3

34.5 ≠ 39

So, correct answer is option (C).
