i passed cat 45.05 % know where to go forMBA in human resourc in mumbai college with 7lakh buge

Since your score is at the lower side I would suggest you to reappear for the CAT examination next year. With this score it is not possible to get an interview call from any of the good B Schools.
If you have appeared for other entrance tests like XAT, SNAP, CMAT etc you can use that score for your admission.

even some of the mba colleges in mumbai like

ITM NAVI MUMBAI REQUIRES 60 PERCENTILE

GURUNANAK INSTITUTE OF MANAGEMENT STUDIES REQUIRES 55 PERCENTILE

so if u want to get admission in Bschools do reappear and write others exams too

ALL THE BEST
