I need a single room in lalpur

Hii, i recently shifted to Ranchi, im in brother's academy and I took a boys hostel which charges 9k for double bed (my room) and 12k for single bed and want to leave this hostel next month or soon, can someone please HELP me to get a single room hostel or flat or pg(suitable for students) i can manage upto 3km from brother's or Nuclear mall. My budget is 9k(tentative) which should include food for 3 time, a bed , washing machine and private washroom (if possible). Not asking for a luxurious furniture but atleast it should define the price like i don't want very low quality furniture at a low or mid price. I can pay upto 6k for just room and other facilities and extra for mess upto around 3k. A little help would be grateful too !!!!
