In a group of six women, there are four tennis players, four postgraduates in Sociology, one postgraduate in Commerce and three bank employees. Vimala and Kamla are the bank employees while Amala and Komala are unemployed. Komala and Nirmala are among the tennis players. Amala, Kamla, Komala and Nirmala are postgraduates in Sociology of whom two are bank employees. If Shyamala is a postgraduate in Commerce, who among the following is both a tennis player and a bank employee?
- (a) Amala
- (b) Komala
- (c) Nirmala ✓ UPSC's answer
- (d) Shyamala
Why the answer is (c)
• The four Sociology postgraduates are Amala, Kamla, Komala and Nirmala, and two of them are bank employees.
• Amala and Komala are unemployed, so the two bank employees among them are Kamla and Nirmala.
• Nirmala is also one of the tennis players.
• So Nirmala is both a tennis player and a bank employee, option (c).
Why the other options are wrong
- (a) Amala
- Amala is unemployed, so she cannot be a bank employee.
- (b) Komala
- Komala is unemployed, so she cannot be a bank employee.
- (d) Shyamala
- Shyamala is a postgraduate in Commerce, not Sociology, and is not identified as a bank employee or tennis player in the constraints.
