Fathers age is 5 times his son’s age. 4 years back the father was 9 times older than son. Find the fathers’ present age.

• let. son age=x
  fathers age=5x
  4 years back, so (x-4)=(5x-4)
  then father was 9 times older than son so, 9(x-4)=(5x-4).....(1)
  solving eqn (1), x=8
  and fathers age =8*5=40 years ANSWER..

• 40 years..
  let fathers present age be x and sons be y..
  x=5y..
  x-4=9(y-4)
  solve both and get the ans

• (x-4)/(5x-4)=1/9
  x=5
  fathers age=5*8=40years

• Let son age is x and father age is 5x,
  4 years back
  son age is x-4
  Father age is 9(x-4)
  x-4 = 9x-36
  by solving this x=4
  then come to present time that is add 4 years into x
  so son age becomes 8 years
  and father is 5 times of son age i.e 40 years

• let the age of son is s
  then his fathers age is 5s
  5s-4=9(s-4)
  32=4s
  s=8
  so fathers age is 5s=5*8
  =40 yrs

• let son's present age is x and father's present age is 5x. 4 years back son's present age is x-4 and father's present is 5x-4.but it is given in the problem that father;s age 4 years back is 9(son's age).
  so,5x-4=9(x-4)----> 32=4x and x=8(son's age) 5x=5*8=40.(father's age).

• 40 as
  5s-4=9s-36
  s=8
  f=5s
  f=40

• fathers sons
  5x x :present
  5x-4 x-4 : 4years back
  now,5x-4=9(x-4)
  x=8
  present age=5x=5*8=40 years

• Let father's present age be x and son's present age be y
  x=5y
  x-4=9(y-4)
  y=8
  x=40
  Father's present age is 40

• son age is=5x
  4 year is back father was 9 times old than son=9(x-4)
  5x-4=9(x-4)
  x=8
  father age=5*8
  =40
• 7 years agoHelpfull: Yes(0) No(1)
• lets son age=x
  father age=5x
  (5x-4)=9(x-4)
  4x=32
  x=8
  
  father age =5x
  put the x value=5*8=40
  
  age of father=40

• Note:
  Here mentioned that 9 times older than not 9 times of
  so, in according to me,
  
  
  4 years back
  Let son x years and father y years
  according to question
  y = 9x+x
  y = 10x
  present
  son = x+4
  Father = 10x+4
  according to question
  10x+4 = 5(x+4)
  5x = 16 => x = 16/5
  Present age of father = 10x+4 = 32+4 = 36 years
• 6 years agoHelpfull: Yes(0) No(1)
• father=5x,son=x
  5x-4=9(x-4)
  x=8
  so father =5*8=40

• current age of son = x
  then currently father is 5x
  four years ago :-
  son:- x-4, father:- 5x-4
  acc. to given condition
  9(x-4) = 5x-4
  
  on solving this we get x = 8 :- current age of son
  we know current age of father is 5x= 40

• 40 years
  4yrs back
  Son=x
  Father=9x
  Now
  Son=x+4
  Father=9x+4
  So, 9x+4=5(x+4)
  =>9x-5x= 20- 4
  =>4x= 16
  =>x=4
  So present age of father=(9×4)+4= 40 yrs
