The question likely refers to the number of Indian States having a bicameral legislature (both a Legislative Assembly and a Legislative Council), analogous to having "both Houses of Parliament" at the Union level. As of late 2020, the states with bicameral legislatures are Andhra Pradesh, Bihar, Karnataka, Maharashtra, Telangana, and Uttar Pradesh. There are exactly 6 such states. Jammu and Kashmir had a bicameral legislature before its reorganization into Union Territories in 2019. Several other states have proposed creating a Legislative Council, but as of now, only these 6 have them.
