Hi KANNAN Kandasamy !

The result of JEE MAINS exam has not declaraed . So, I think 72 is her percentile . You can use Careers360 Rank Predictor to know the probable rank . Here is the link provided :-

hello sir 

we can not say anything right now , wait untill the result and ranking will be declared( till april exam's result).

but you can calculate approximately rank by: (100-percentile scor)*total number of students/100

it comes out to be more than 2lakhs( varies depending upon the total students in april and their results).( general rank)

And admission will depend upon rank , category and state.And i think she may get seat due to quota but she has to compromise with branch and place.So lets see what will be the result/ exact ranking

Seeing this i would suggest to score more in april exam to take admission in good state government college or in good private college.

Good Luck
