Arun

From the above mentioned diagram Navin is 12th from right end

and Arun is 5th from left end.

As the question says, if Navin shifts by 3 places towards left (that is towards arun), he will become 15th person from the right end.

It is given in the question that he will be 10th person from the left end.

The same can be summarized in the below mentioned diagram.

Therefore, Navin is 10th from left end and 15th from right end.

Total number of children in a row is

$9+14+1$(navin himself) $\to 24$

Hence, total number of children $\to 24$
