Harry is three times as old as Tim. In eight years, he will be twice as old as Tim. How old was Harry three years ago?

• Harry was 21 years of age three years ago.
  
  Present age of Harry = 24. age of Tim =8 yrs
  After 8 years, age of harry = 32, age of Time will be 16 years.
  
  If present ages of Harry and Tim are H and T respectively, then
  
  H=3T, T = H/3
  and
  (H+8) = 2*(T+8) = 2T+16 = 2*H/3 +16
  H/3 = 8
  H=24 years.
  
  so Harry was 21 years of age three years ago.

• ans- 21
  let harry is x yr old & tim is y yr old
  x = 3y......(1)
  after 8 yr:
  (x+8) = 2 (y+8).....(2)
  solving this
  x= 24 & y= 8
  Hence before 3 yr Harry was (24-3) = 21 yr old

• tim=x
  harry=3x
  3x+8=2(x+8)
  x=8
  harry=24
  3 years ago age will be,21 years.

• h=3t
  h+8=2(t+8)
  =>t=8
  =>h=24
  3 years ago harry age is 21
• 11 years agoHelpfull: Yes(0) No(1)
• let present age of tim is x
  than present age of harry is 3*x
  in eight years
  (3*x+7)=2*(x+7)
  present age of tim is x=7
  and harry's age is 21
  in eight years tim age will be 7+7=14
  and harry age will be 21+7=28
  so before three years harry age was 21-3=18
  answer is 18

• Harry age 3 years ago is 21 .
  
  Lets present age of Harry = H and Tim = T .
  given that H = 3T ...................(1)
  and in 8 years , H + 8 = 2*(T+8) ......................(2)
  replacing T = H/3 in e
