Currently, the age of a father is three times that of his son. 2.5 years from now, age of the father becomes 2.5 times that of the son. The age of son currently is?

• Let current age of son=x
  father=3x
  Now, (3x+2.5) = 2.5*(x+2.5)
  x=7.5 year ans.

• the age of son is 7.5 years
  eq-1 is x=3y
  eq-2 is x+2.5=2.5(y+2.5)
  by solving that two eqs we get y=7.5

• suppose current age of
  son=x and
  father=3x
  
  Now, (3x+2.5) = 2.5*(x+2.5)
  
  x=7.5 year

• let age of son = x;
  then father = 3x;
  3x+2.5 = 2.5*(x+2.5)
  3x+2.5 = 2.5x+ 6.25
  .5x = 3.75
  x = 3.75/.5 = 7.5 year

• f=3s
  f+2.5=2.5(s+2.5)
  3s+2.5=2.5s+6.25
  s=7.5

• let the current age of son is x then age of father will be 3x
  now after 2.5 yrs,
  3x+2.5=2.5*(x+2.5)
  x=7.5yrs

• Let current age of son=x
  father=3x
  Now, (3x+2.5) = 2.5*(x+2.5)
  x=8 year ans.

  3x+2.5 = 2.5x+ 6.25

  x = 3.75/.5 = 7.5 years or 90 month

• present age of son is'x'. then father's present age will be ' 3x'.
  affter ' 2.5'years,
  (3x+2.5)=2.5(x+2.5)
  then the present age of son is '7.5'

• Ans==> 7.5
  now: f=3s ---------------(1)
  after 2.5 yrs : (f+2.5)=2.5 (s+2.5) ----------(2)
  solving (1) & (2) s=7.5

• age of son be x
  age of father be 3x
  after 2.5 year
  age of son x+2.5
  age of father 2.5(x+2.5)
  now
  3x+2.5=2.5(x+2.5)
  now we get x=7.5

• ratio of father and son will be 3x:x;
  2.5 years form now father 3(x+2.5) and son (x+2.5)
  the equation will be 3(x+2.5)= 2.5 (x+2.5)
  then x=2.5 is the answer
• 9 years agoHelpfull: Yes(0) No(0)
• from equation,
  (3.x+2.5)=2.5*(x+2.5)
  x=7.5 years

• ans= 5yrs
  7.5 yrs is after 2.5yrs, so 7.5-2.5=5yrs

• Let son's=x. so, father's=3x
  [after 2.5]
  3x+2.5=2.5(x+2.5)
  x=7.5
  [currently]
  x=7.5-2.5=5
  x=5
