Question

In 1990, a person is 15 yrs old.
In 1995 , that same person is 10 yrs old. How can be this?​

Answer 1

Explanation:

In 1995 BC if a person is 10 years old, then after 5 years, that is 1990 BC, he'll be 15 years old! B.C. stands for Before Christ, and it means the number of years before the birth of Jesus Christ.

Answer 2

Answer:

If the year 1990 and 1995 are in BC i.e. if they are 1990 BC and 1995 BC.

Explanation:

In case of BC, the year is moving backward for BC. Here BC stands Before Christ. In this case 1995 BC will come earlier than 1990 BC.  As a result the person is 10 years old in 1995 BC and the same person is 15 years old.
