Father's age was five times his son's age 5 years ago and will be three times the son's age after 2 yrs. what is the ratio of their present ages?

• let son's present age is = x year
  so son's age 5 year ago was (x-5)
  and father's age was 5(x-5) that time
  and after two years son's age would be (x+2)
  and then father's age would be 3(x+2)
  hence it is clear that 5(x-5)+7 = 3(x+2)
  and after solving we get x = 12
  so son's present age is 12 years and so father's present age is 5(12-5)+5=40
  s0 the ratio of present age of father and son respectively is 40:12 or10:3

• father:son=10:3

• 3/10..... solve for the eqn y-5 = 5(x-5) & y+2 = 3(x+2) where y & x is the present age of father n son resp...

• F-5=5(S-5)
  F+2=3(S+2)
  F: PRESENT AGE OF FATHER
  S:PRESENT AGE OF SON
  SOLVING WE GET F=40, S=12
  THUS F:S=10:3

• let son-x, father -5x so presnt age-x=5,5x=5
  eq- 5x+5+2=3(x+5+2), x=7
  then present age-12,40 there ratio 3/10

• ans is 40:7
