What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘− ’ are interchanged and ‘×’ and ‘÷’ are interchanged?
8 ÷ 5 + 20 × 4 - 9 = ? 

8 ÷ 5 + 20 × 4 − 9 = ? 
Rule: + ↔ − and × ↔ ÷

After Interchange the sign equation will be:

? = 8 × 5 − 5 + 9

? = 40 − 5 + 9

? = 49 − 5

? = 44

Thus, the correct option is: (d)
