A grand father has 3 grand children. Age difference of two children among them is 3. Eldest child age is 3 times the youngest child’s age and the eldest child age is two year more than the sum of age of other two children. What is the age of the eldest child?

• 15 yrs
  
  If ages are
  x,x+3 and 3x , then
  3x= x+x+3+2
  x=5
  Age of eldest son = 3x=15 yrs

• take ages x,y,z;
  y-x=z-y=3;=>y=x+3;
  z=3x;=>z=x+y+2 =>z=2x+5;
  .ie 3x=2x+5=>x=5 then z=15

• 3 yrs is the age of eldest child..
  let ages b x,y,z yrs(x>y>z
  x-y=3
  x=3z
  x=2+y+z
  solving these we get x=3
