hey neeraj,
since current through 7ohm resistor is 0
therefore current of 3A will pass through 5ohm resistor...
now consider,only one big loop consisting of 10,5ohm resistor and cell..apply kirchoff law ull get the answer as E=45V
now,to find current in 7.5ohm resistor take the loop consisting of 5,7,7.5ohm resistor...apply kirchoff law ull get the answer as 2A
similarly u can check the other option:
(i ve checked for only the answer u hve given).
