Solution
Ajay is the gun
Bhuvi is the robot
Chandu is the missile
Bhuvi is not the gun, since if she is, then Ajay would also be the gun. It is contradictory. Therefore, we can conclude here that Bhuvi is a robot who can either lie or tell the truth.
Chandu is also not the gun since his statement would then be a lie. Hence, we get a conclusion here that Chandu must be the missile that always lies.
Therefore, Ajay is the Gun, Chandu is the missile, and Bhuvi is the robot.
