$\Rightarrow$  The given number is $31520332$.

(A) Place value of 5 in 
$91,25,678=5000$
Face value of 5 in 
$91,25,678=5$
$\therefore :difference=5000-5$
$=4995$ 

Face value of a digit in any place will be the digit itself.

Face values of 5 and 9 are 5 and 9 respectively. 

The difference between $88.888$ and $100$ is,

In the given sequence there are 3 such combinations where an even number is immediately preceded by an odd number and immediately followed by even number.

Let the required number be $n$
Then, $3n+9=45$
$\Rightarrow$  $3n=45-9$
$\Rightarrow$  $3n=36$
$\Rightarrow$  $n=\cfrac{36}{3}=12$
Hence the required number is $12$

Place value of $5$ in
$91,25,678 = 5000$
Face value of $5$ in
$91,25,678 = 5$
$\displaystyle \therefore $ difference  $= 5000 - 5
= 4995$

Sum of face values of all the digits of 
$749205=7+4+9+2+0+5=27$

Lets take an example : $245$- place value for Hundred's place digit is $200$ and face value is $2$.
