RADHA and VIDYA both of them are teachers taking classes for fifth std. RAVI is studying in their class. One day both of them were talking about Ravi, when Vidya told Radha that "Ravi is the son of a Judge". Immediately RADHA said," No,No. Ravi is the son of a Doctor, I know his father very well. He is Dr. Ramachandran". But what Vidya told is also correct. How can a Doctor be a Judge also?
