Seven friends, Kamala, Raveena, Amruta, Nisha, Gautami, Bhavana and Triveni, are sitting in a circular dining table facing the centre (but not necessarily in the same order). Raveena is sitting second to the right of Nisha. Gautami has Kamala and Triveni as immediate neighbours. Triveni is sitting third to the left of Nisha. Amruta is not an immediate neighbour of Nisha. Who is seated fourth to the left of Bhavana?
