Please tell me how to solve this problem. Though I know it can be solved by Kirchoff’s Junction rule, please give me the working. Thanks.

There is no need to apply any KVL or KCL.

As from common sense or from knowledge,

we can directly say that current through 2 ohm resistor will be zero.

Because if current get passed through the 2 ohm resistance then there is no another way or path  for returning that current as same current cannot be passed through the same resisance in opposite direction.

There will be only one direction for the current.
