How many people not recommended by at least one of the first two interviewers, Mr Xavier and Ms Yana, were finally selected for the job?

If someone is not recommended by both the first two interviewers, the person is straightway rejected.
If exactly one of them recommends, the person is interviewed by Zen. Thus, all 43 interviewed by Zen fall in this category and 28 recommended by Zen are selected......Therefore, can be answered

Let me know if you do not understand

A person is selected the moment that person is recommended by two of the interviewers. That is, a person recommended by both the first and the second person is not interviewed by the third person. Also, the third person does not interview a person rejected by both the first and second person.

Select Yes if the question can be answered from the information given above. Otherwise, select No if the question cannot be answered. ­

A simple but tricky question.

How many people were not recommended by Xavier?
Xavier interviewed 87 and recommended 45, so he did not recommend 87-45 or 42.....Therefore, can be answered

Which interviewer had the maximum of his interviewed candidates selected for the job?
Now, Zen has 28 out of 43 or around 65% of his interviewed candidates selected.
Both, Xavier and Yana interviewed 87 candidates, and if we take that all 51 recommended by Yana were selected, the % is 100* 51/87 or 59% approx.
Thus Zen is the answer always....Again, can be answered

Solution Yes, Yes, Yes

ribbons, hope it helps


 

­For the third question it says that the number of people who got *accepted* for the job. The percentage we find is the number of people who got recommended for the job. For example, for the Ms yana, 51 are recommendation, we do not know out of 51 how many got actually selected. right?
