19.******* An old toy had three grandchildren, the difference between two children was 3 years. Her eldest grandchild was 3 times elder than the youngest one and the elder one 2 years more than the sum of the other two. Then what is the age of the eldest child?

• three children a,b,c
  c is the youngest,a is the eldest
  b-c=3
  b=c+3
  a=3c
  a=b+c+2
  3c=c+3+c+2
  c=5
  Therefore,a=15

• let the 3 children be x,y,z with x as eldest,y as elder and z as younger
  x=3z
  y=x+z+2=4z+2
  y-z=3
  4z+2-z=3
  z=1/3 which is nt possible
  also x-y=3
  3z-4z-2=3
  z=-5 which is nt possible
  also x-z=3
  3x-x=3
  x=3/2 which is again nt possible so ques is wrong
