It's not clear how 3 becomes into no. I do not see no dependency.

your expected output is not clear make sure it correct.what is the use of "BMI" column in both tables?

This is your second interview question today: at least this is slightly more complicated than your first one.
To fetch data based on dates can anyone help me with this...and he gave me the INPUT and OUTPUT too[^]

You are not ready for this job, and our giving you the solutions to them all helps no-one - not you, who will be out of his depth as soon as the interviewer asks about the detail; the company that might employ you on the basis of our knowledge rather than yours; or the applicants that can do the job which you might displace by this blatant cheating.

Learn your subject, apply for jobs you can do: or you are setting yourself up for a fall.
