My approach..
Area of circle is 100pi approx 314.
Area of square is 576
Fraction= (576-314)/576
262/576
50% of 576 is 288..
It has to be slightly less than 50% so E

Given radius=10 & Side=24
Area of circle=πr^2=3.14*10^2=314
Area of square=(Side)^2=24^2= 576
Required Fraction= Area not covered by circle/Total area of square=(576-314)/576=262/576 =131/288 =slightly less than 1/2
Since,9/20=0.45 closed of all choices,answer should be E.
