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?
AnswerUPSC’s answer is (c).
The six women are Vimala, Kamla, Amala, Komala, Nirmala and Shyamala. Three are bank employees, and Vimala and Kamla are two of them. Among the four Sociology postgraduates (Amala, Kamla, Komala, Nirmala), two are bank employees; Amala and Komala are unemployed, so those two are Kamla and Nirmala. The bank employees are Vimala, Kamla and Nirmala. Nirmala is also a tennis player, so she is both.
Why each option is right or wrong
- (a) Amala is unemployed, so not a bank employee.
- (b) Komala is unemployed, so not a bank employee.
- (c) Correct: Nirmala is a tennis player and, by elimination, a bank employee.
- (d) The three bank employees are Vimala, Kamla and Nirmala, so Shyamala is not one.
