the sum of ages of sunil and father is 78 years,,6 years hence fathers age will be twice of sunil age.find the present age of sunil and father?

• let the sunil age =x
  father's age=78-x
  after 6 years sunil's age=x+6;
  after 6 yeares father's age=84-x;
  after 6 years fathers age is equal to the twice of sunil-s age
  so,
  84-x=2(x+6)
  3x=72
  x=24;
  present age of sunil=24years;
  present age of sunil's father=78-24=54

• 24 & 54 years
  
  If presents ages(in years) of Sunil=S & Father=F, then
  S+F=78 ---(i) &
  2(S+6)=F+6 or 2S-F= -6 ---(ii)
  From (i) & (ii), S=24, F=54

• by solving the above equations ,ans is-son=28 & father=50
• 8 years agoHelpfull: Yes(0) No(3)
• age of son=24
  age of father= 54.
  x+y=78
  2(x+6)=y+6
  solve for x and y

• let age of sunil=x
  sunil+ father=78
  after 6 yrs sunil+father=78+12 bcs 6 yrs incrs of sunil and also his father
  now father age wll be twice =2x
  x+2x=78+12
  3x=90
  x=30
  now present age of sunil=x-6=30-6=24
  father =2x=2*30=60-6=54

• Sunil's age + Father's age = 78 -----------(i)
  
  after 6 years
  Father's age + 6 = 2(Sunil's age + 6)
  from eq. (i)
  
  78 - Sunil's age = 2(Sunil's age) + 12
  3(Sunil's age) = 72
  Sunil's age = 24 ANS
  
  So from eq. (i)
  father's age = 78 - 24
  = 54 ANS.

• sum of ages of Sunil and Father x+y=78
  6 yrs hence 6+y=2x
  x=28
  y=50
• 8 years agoHelpfull: Yes(0) No(2)
• let ages of sunil and father be x and 78-x
  x+y=78
  6 years hence 84-x=2(x+6)
  3x=72
  x=24
  y=54

• Let, Sunil = S & Father = F
  .`. (s+6) + 2(s+6) = 78 + 6 + 6
  => S = 24
  So, F = 78 - 24
  = 54

• age of sunil and father=x-78
  2(x-6)
  78+6=84
  84-x=2x-12
  3x=72
  x=24
  so sunil age is 24-78=54
