Try and get all the denominators the same, i.e. in terms of 900:
I: 47x6/150x6 = 282/900
II: 111x3/330x3 =:(approx) 333/990
III: 299/900
From the above, we know that I is the smallest (as it has the smallest numerator) and hence comes first, eliminate options C,D and E. Only left with A & B.
299/900 will definitely be greater than 333/990 as if we find the accurate multiple by which to get 900 in II, it will give us a numerator being less than 299. Hence III<I
Final order: I,III,II
Option B
