If 'A' stands for '$÷$ ', 'B' stands for '$\times$ ', 'C' stands for '$+$ ' and 'D' stands for '$-$ ', what will come in place of the question mark ($?$) in the following equation?
$$\text{70 D 11 B 5 C 45 A 9 = ?}$$

Substitute the operators with their respective arithmetic symbols as given:
* Replace A with $÷$
* Replace B with $\times$
* Replace C with $+$
* Replace D with $-$

The equation becomes:

$$\text{70}-11\times 5+45÷9=?$$

Applying the BODMAS rule:

1. Division: $45÷9=5$

$$70-11\times 5+5=?$$

2. Multiplication: $11\times 5=55$

$$70-55+5=?$$

3. Addition: $70+5=75$

$$75-55=?$$

4. Subtraction: $75-55=20$

Therefore, $?=20$.
