The correct answer is
$25$

Calculating Row Members Position

To find the total number of members in the row, we need to consider the position of 'A' from both ends.

'A' is the 16th person from the left side. This means there are 15 people to the left of 'A'.

'A' is the 10th person from the right side. This means there are 9 people to the right of 'A'.

Determining Total Members

The total number of members in the row can be calculated using the formula:

$Total Members = (Position from Left) + (Position from Right) - 1$

The subtraction of 1 is necessary because 'A' is counted in both positions (from the left and from the right).

Substituting the given values:

$Total Members = 16 + 10 - 1$

$Total Members = 26 - 1$

$Total Members = 25$

Therefore, there are 25 members in the row.
