A husband and wife have a combined age of 91.

The husband is now twice as old as his wife was when he was as old as she is now.

How old are they..?

• suppose the age of husband is x,wife is y years
  x+y=91(given)
  now let diff between their ages be x.that is x-y=k.
  now when husband is y yaers old, his wife must be y-k years old
  x=2(y-k)(given)
  so 2y-x=2k. and x-y=k.eliminating k we get 4y=3x. but x+y=91, so solving these
  two x=52 y=39.(ans)
  
  
  
  
  old.

• husband age=x,wife age=y
  x+y=91
  x=2(y-(x-y))
  =>3x-4y=0
  solving we get x=52&y=39
