In a row of $85$ people, Anusha is $30\text{th}$ from the left side and Bhanu is $18\text{th}$ from the right side. Find the number of people who are sitting exactly between them.

Let's find the number of people sitting between Anusha and Bhanu.
* Total number of people in the row = $85$
* Position of Anusha from the left end = $30$
* Position of Bhanu from the right end = $18$

The sum of positions from both ends is:

$$\text{Left Position}+\text{Right Position}=30+18=48$$

Since the total number of people ($85$) is greater than the sum of their positions ($48$), there is no overlapping.
The number of people sitting between them can be found using the formula:

$$\text{Number of people between them}=\text{Total number of people}-(\text{Left Position}+\text{Right Position})$$

$$\text{Number of people between them}=85-48=37$$

Thus, there are $37$ people sitting exactly between Anusha and Bhanu.
