Hello,

WBJEE means West Bengal Joint entrance examination. So if you are qualified for WBJEE then you will get admission in West Bengal engineering college government or private colleges. But with this rank you can't get admission in mumbai college. Because it's belong Maharastra state. If you want to go mumbai then apply JEE mains examination. But if you want to take admission then you can apply WBJEE infact apply for JEE mains examination also.

All the best.
