ABCD is a square. E and F are the midpoints of sides CD and BC, respectively. What is the ratio of the shaded region area to the unshaded region?
Answers.
A) 1:1
B) 2:1
C) 3:1
D) 5:3
E) 8:3
Let's join the midpoints as shown in the figure then we'll get four small squares...   AODX be 1 and similarly all squares..and we can split the unit 1 into half and half as per the mid points...   Then shaded will be 1+1/2+1/2+1/2 = 5/2   and unshaded is 1/2+1/2+1/2 = 3/2..   shaded : unshaded is 5:3..   ANS option 5:3.
