Solution: 
Given: There are a total of 88,000 employees out of which $\frac{3}{8}$ are posted in Northern India and rest are posted in Southern India.
Fraction of employees posted in Southern India = $1-\frac{3}{8}=\frac{8-3}{8}=\frac{5}{8}$
Number of employees posted in Southern India
$$\begin{gathered} =\frac{5}{8}\times 88000 \\ =5\times 11000 \\ =55000 \end{gathered}$$

So, 55,000 employees are posted in Southern India.
