Direction: Read the following information carefully and answer the questions given below:

There are eight people: Ashu, Dishu, Krishu, Mishu, Nishu, Rishu, Prishu, and Vishu. They all were born in different years viz. 1973, 2001, 1985, 1979, 2004, 1989, 1995, and 1998 but not necessarily in the same order. But the date and month of birth of all these persons are the same. The calculation is done with respect to the present year 2021 and assuming months and date to the same. 

The age of Mishu is a prime number. Two people were born between Mishu and Nishu. Two were born between Rishu and Ashu. The difference between the age of Nishu and Prishu is 6years. The age of Prishu is not divisible by 8. The age of Krishu is divisible by 4 but he is neither the eldest person nor was born adjacent to Nishu. Rishu was born just after Krishu. Dishu was born just before Ashu.
