4. C
   In case switch A is off in the second setting, it necessarily follows that A is on in the initial setting based on the assumption stated in the fourth condition i.e. for any other initial setting, turn off all switches that are on and turn on all the switches that are off. By the same assumption and through the process of elimination of the other two switches in the second setting to be in B on, C off. Thus the initial setting in this case would be : A on, B off, C on.

5. B
   Applying the condition i.e. for any other initial setting, turn on all switches that are off and turn off all switches, if any, that are on. Then if : A off, B on, C off then A on, B off and C on.

6. D
   When only one switch is off in the second setting and if we use assumptions 1 and 3, then A on B off C off ® A on B on C off or A on B on C on ® A on B on C off. So both these possibilities are not correct. Then using the fourth assumption and by the process of elimination, A off B on C off in the initial setting result in A on B off C on in the second setting.

7. B
   The equation given is P i.e. stop three and M is stop six. Now in case N is stop 4, then 5th stop is L. As it is mentioned N is the stop immediately before L. Now stops 1 and 2 remain and from the given equation O is the stop immediately before Q, O is 1 and Q is 2. Thus the stop immediately before P is Q.
