Question

In 1990, a person is 15 years old.

In 1995, that same person is 10 years old.
How can this be?

Answer 1

Well, if this were to be
`BC`= Before Christ, the years would go back.

Step-by-step explanation:

And that's why the question is trying to trick you. So in 1990 BC the person is 15 years old. 5 years later, the same person is now 10 years. 5 years back is the order of the BC concept. Hope this makes sense!
