Arranging in the order of wealth :
Statement I: Jayanti = Indu
Statement II: Ramesh > Kanu, Jayanti < Ramesh
Statement III: Jayanti > Ram > Kanu, Ramesh > Ram
Statement IV: Ramesh < Navneet = Navneet > Ramesh
Combining all the above four we get, Navneet > Ramesh > Jayanti > Ram > Kanu
Hence, the required answer is (3).
