The total of the ages of X, Y and Z is 65 years. Three years ago, the ratio of their ages was 3: 5: 6.What is the difference between the present ages of X and z

• 12 years
  
  If the age before 3 years of x,y & z are 3x,5x & 6x respectively
  present age=(3x+3)+(5x+3)+(6x+3)=65, 14x=56, x=4
  Present ages of x=15,y=23,z=27
  Difference z-x=27-15 =12

• let present age x+3,y+3,z+3
  then,x+3+y+3+z+3= 65
  x+y+z=56
  now
  3years ago
  x/3=y/5=z/6
  solving two equations
  we get x=12,y=29,z=24
