If mass of moon is already given (point 2) in the option then why do u bother to find it again? Please check your question again.
 I think in step 2 it should be mass of earth rather than that of moon.
 
So if this is the case then to find mass of moon you can use Kepler's Law of planetary motion
 
           T2 = 42R3 /GM
 
The Scientist does not study nature because it is useful; he studies it because he delights in it, & he delights in it because it is beautiful. If nature were not beautiful, it would not be worth knowing, life would not be worth living. Ofcourse I do not here speak of that beauty that strikes the senses, the beauty of qualities & appearances; not that I undervalue such beauty, far from it, but it has nothing to do with science; I mean that profounder beauty which comes from the harmoniuos order of the parts, & which a pure intelligence can grasp.
