Show answer & explanation
Correct answer: A
Explanation
Based on the given clues, we can deduce the profession of each person step-by-step:
• Rajesh: Given directly as Scientist.
• Thomas: Thomas is either Doctor or Architect. But Doctor is either Aravind or Sunil, which means Thomas cannot be the Doctor. Thus, Thomas = Architect.
• Kapil: Kapil is either Architect or Lawyer. Since Thomas is the Architect, Kapil = Lawyer.
• Kranthi: Kranthi is either Lawyer or Professor. Since Kapil is the Lawyer, Kranthi = Professor.
• Remaining persons: Aravind, Sunil, Lala
• Remaining professions: Doctor, Engineer, Journalist
• Lala: The Doctor is either Aravind or Sunil, and Lala cannot be the Engineer. Therefore, Lala = Journalist.
• Sunil & Aravind: Since Sunil is not the Engineer, Sunil = Doctor. Consequently, Aravind = Engineer.
Hence, Aravind is the engineer.
