33*Charge on opposite face is negative of each other....
*In the conductors which are isolated charge is conserved....
*Potential of connected spheres are same....
these three will solve the problem.
4 concentric hollw spheres of radii R(1),2R(2),3R(3),4R(4) has given the charges as shown
then 1&3,2&4 were connected
1. find charge on the inner surface of 3rd conductor
2. charge on the forth conductor
3. the potential of conductor 1 & 2
