If you have a number X, 3 times that number is 3x.

It is not incomplete, depends on another variable.

If he soon is represented by the variable Y, "times older than his son"
means 3Y, not 3+Y

Title:
  logic error in a logic puzzle

Status in “gbrainy” package in Ubuntu:
  New

Bug description:
  Binary package hint: gbrainy

  This bug seems related to bug #622197, but it is about the language which is in error.
  The text of the question is "Johnś age is nowadays 2 times his son's age. 12 years ago. John was 3 times older than his son."

  What is meant, apparently, is "John was 3 times AS OLD AS his son".
  "3 times older than" is nonsense, but as far as one absolutely wants to attach a meaning to it, it must be "4 times as old".
