Q. There was a community in which there were 1000 couples.In that 2/3rd of men who r taller r also heavier n 3/4th of the men who r heavier r also taller n there were 120 women who were both heavier n taller than men.So how many men r both taller n heavier than men?

• Answer is 330
  
  Number husbands taller than wife = x
  
  Number husbands heavier than wife = y
  
  Number of husbands taller and heaview =z
  
  2/3*x=z=3/4*y
  
  x=3/2 z
  
  y=4/3 z
  
  x+y-z+120=1000
  
  (3/2+4/3-1)z=1000 -120=860
  
  z=3/8*880=330
