Question 60: Logical Reasoning and Mental Ability
In a group of six women there are four dancers, four vocal musicians, one actress and three violinists. Girija and Vanaja are among the violinists while Jalaja and Shailaja do not know how to play on the violin. Shailaja and Tanuja are among the dancers. Jalaja, Vanaja, Shailaja and Tanuja are all vocal musicians and two of them are also violinists. If Pooja is an actress, who among the following is certainly a dancer and a violinist ?
AnswerUPSC’s answer is (d).
There are three violinists: Girija, Vanaja and one more. Of the four vocal musicians (Jalaja, Vanaja, Shailaja, Tanuja), two play the violin. Vanaja is one, and Jalaja and Shailaja are not violinists, so Tanuja is the second. Tanuja is also a dancer, as given. So Tanuja is certainly both a dancer and a violinist. Pooja is the actress.
Why each option is right or wrong
- (a) Jalaja does not play the violin.
- (b) Pooja is the actress; nothing says she dances or plays the violin.
- (c) Shailaja is a dancer but does not play the violin.
- (d) Right. Tanuja is a dancer and the second vocalist who plays the violin.
