In the square above, 12w = 3x = 4y. What fractional part of the square is shaded?
a)2/3 b) 14/25 c) 5/9 d) 11/25 e) 3/7

• let w = 1, x = 4, y = 3
  area of square = (w+x)^2 = (5)^2 = 25
  area of unshaded region : (1/2*1*4) + (1/2*1*4)+(1/2*1*2)+1/2*4*3)
  =2+2+1+6 = 11
  area of shaded region/area of square = (25-11)/25 = 14/25
  
  Therefore, B

• let 12w=3x=4y=k
  =>w=k/12,x=k/3,y=k/4
  =>x+y+w=2k/3
  so 2/3 is correct ans
