Statement 1 NOT SUFFICIENT. [r,s] can be, [1,15] [3,5] [5,3] and [15,1]
Statement 2 NOT SUFFICIENT, [r,s] can be [1,7] [2,6] [3,5] [4,4] [5,3] [6,2] [7,1]
Combining STATEMENT 1 AND STATEMENT 2, [r,s] can be [3,5] or [5,3]
Therefore r/s= 3/5 = 0.6 or r/s = 5/3 = 1.667
Therefore we are not sure whether r/s =3/5 OR 5/3
Hence option (E) Statements (1) and (2) TOGETHER are NOT sufficient is the answer
