my brother completed 10th now which side is better to growth

First of all, accept my congratulations for your brother for completing his 10th grade.

After that, it is not mine, community or anyone else's choice to bring that young fellow to any side.

 

It should always be his choice to choose his path and the future. He knows best what he likes... Then you should know what he should do with his interest and where he should apply the potential.

 

First of all, look at his grades. Which subject was his best. What does he do in his daily life, does he like computer, does he like art, does he like sports. Then make a choice. Always consider his potential before making a decision.
