The mass enclosed within the Large Magellanic Cloud\'s orbit of the Milky Way, at 48 kpc, is how many times the mass enclosed within our orbit of the Milky Way, at 8 kpc?

A. 1

B. 2    

C. 4

D. 6

E. 8

Solution

the answer should be D.6. as 48/8=6. But there is some partial mass missiing due to existence of dark matter. So it should be 6 but theorists are still working to resolve this matter. this is still a kind of open problem. So apparently and rightly till now the answer will be 6
