In Hindu mythology, Nahusha and Ashok Sundari are two different characters who belong to different generations, so it’s not accurate to compare their ages.
Nahusha was a king and a descendant of the lunar dynasty. He was the son of Ayu and the father of Yayati. According to the story in the Mahabharata, Nahusha became arrogant and was cursed to become a snake. Later, he was freed from the curse by the sage Agastya.
On the other hand, Ashok Sundari is a lesser-known character in Hindu mythology who is believed to be the daughter of Lord Shiva and Parvati. She is not mentioned in the ancient texts like the Vedas, Puranas, or the Mahabharata, but is rather a part of the modern-day folklore and popular culture.
So, there is no basis to compare the ages of Nahusha and Ashok Sundari as they are from different stories and different periods of time in Hindu mythology.
