I want to activate a SPDT relay with the help of a LDR. The resistance of LDR is 900 Mohm in dark and around 9 ohm when max amount of light falls on it. I have a dc supply of 6V. Please give some circuit ideas on how to solve the above problem?

Post that in your other thread! Also, add the relay specifications if you have one. Please do not start additional threads. Your other thread can be found here.
Additionally the circuit that Mike provided can be easily modified for 6 volt operation. I suggest you look it over.
