Dear Student,

It depends on the number of partner you have, because 1BHK has much space campare than 1RK, 1BHK Includes one bedroom, one hall, and one kitchen while 1RK includes one room and one kitchen only. So you are planning to live alone then 1RK will be best for you as you also don't need to pay much money and you will find it affordable. Still if you want some place other than bedroom then 1BHK is best for you, so that you can create your own corner besides bedroom. Decision is now totally up to you whether you go with the more space or affordable one.

Good Luck :)
