Sorry for the messy image .
I have got the right answer by assuming certain values of the resistors . But I would like to know whether this question can be done logically without assigning numerical values to the resistors .
Initially when S2 is open and S1 is on position 2 , all the resistors are in series .Same current flows through them . The one with higher resistance will have higher power dissipated and will flow brighter .From this I concluded R2>R1>(R3=R4) .
Now S2 is closed and S1 is on position 1.This makes R2 in parallel with R1 .
Now I assigned some numbers to the resistors such that R2>R1>(R3=R4) and checked the respective i2R values .Then compared it with their initial i2R values .
Could someone suggest an alternative/faster approachwhuch requires lesser calculation to solve this problem .
Thanks
