Correct Answer: It can be possible in only BC ie, Before Christ That was about 2000 years ago Given, In 1990 BC = 2000 + 1990 = 3990 years ago, a person is 15 years Old => In 1995 BC = 2000 + 1995 = 3995 years ago, the same person will be 10 years Old Therefore, In 2000 BC = 2000 + 2000 = 4000 years ago, the same person will be 5 years Old
