Uh.. Looks to me like something you are meant to figure out on your own.

So, @waqarshafiq67 , the first 2 Q's are very straight forward

what do you know about voltage dividers ? surely you have been taught something about them in class ?
Q2 is solvable with a variation of Ohms law, you must have been taught that as well ?

you make an effort to answer and we here will guide you
