Arnab, Anush
It is mentioned that there is at most one person between Ankur and Anush. Therefore,
Case 1:
Arnab, Anush, ___, Ankur
It is mentioned that there are at least two persons between Arnab and Asraf. Therefore,
Aranab, Anush, ___ , Ankur, Asraf
Aranab, Anush, Adi , Ankur, Asraf
Case 2:
Arnab, Anush, Ankur
It is mentioned that there are at least two persons between Arnab and Asraf. Therefore,
