At what age does James become a senior citizen?
What is "four years back then"? Is it 2015-4 = 2011 or some other year?

In 2015, James was three times as old as his daughter Kate. Four years back then, he was four times as old as Kate. In what year will James become a senior citizen?
Another "STUPID" problem, in my opinion.

Anyway, in 2015, he was 36. You need to determine what age is "senior citizen" age, and then answer the question.
