The ratio between the ages of Son and his mother is 1: 2 and that of Son and his father is 1: 3 at the time of Son's birth. If son is 10 years old now. Find out the ratio between the ages of son's mother and father at present.

• I think there is some mistake in statement.
  
  At the time of birth of son, his age is zero.
  Then as per statement,
  age of mother =0*2=0
  age of father = 3*0=0
  
  Or I am confused. :-)
  
  Pls check.

• son=s
  mother=m
  father=f
  
  at time of birth
  s/m=1/2
  m=2s
  s/f=1/3
  f=3s
  
  when s=10
  m=20
  f=30
  =>m/f=2/3

• sun:mother=1*1:2*1=>1:2 using equivalence
  sun:father=1*1:3*1=>1:3
  thats why
  sun:mother:father=>
  1:2:3
