In such kind of questions we need to check the distance from 1/2.
17/35 and 25/52 are smaller than 1/2 and so are out.
for other numbers we need to check the number farthest from 1/2
9/17-1/2=1/34
31/61-1/2=1/122
41/81-1/2=1/162
Clearly value of 1/34 is the most.Hence it is the farthest from 1/2 and our answer.
