27. Question: Between X and Y who is the better dancer? [RRB ALP 09/08/2018 (Morning)]

 Statements:
1. X had given more dance auditions.
2. Y had given more stage performances.

Correct Answer: (b) Statement 2 alone is sufficient while statement 1 alone is insufficient
Solution:

The number of dance auditions given by X or Y does not give the information about who is the better dancer because it does not give any information about the result. So, statement 1 is not sufficient. The number of stage performances given by Y is more than X. So it is clear that the selector has chosen Y over X . So Y is a better dancer than X. So, statement 2 is sufficient . Hence, statement 2 is alone sufficient and while statement 1 alone is insufficient.
