Solution



Given:
    • Each of the n employees at a certain company has a different annual salary

To find:
    • The median of the annual salaries of the n employees

Analysing Statement 1
    • As per the information given in statement 1, when the annual salaries of the n employees are listed in increasing order, the median is the 15th salary.
      o From this we can only say that there are 14 + 1 + 14 = 29 employees in the company, or n = 29
      o But from this statement, we cannot find out any specific value of the median salary, which is the salary of the 15th employee, in increasing order

Hence, statement 1 is not sufficient to answer

Analysing Statement 2
    • As per the information given in statement 2, the sum of the annual salaries of the n employees is $913,500
      o From this we cannot find any information about the median salary, as we don’t have any data about the individual salaries of the n employees

Hence, statement 2 is not sufficient to answer

Combining Both Statements
Combining the information from both the statements, we can write:
    • The median salary is the 15th salary – hence total number of employees will be 29
    • The sum of the annual salaries of all the employees is $913,500
      o From this, we can find out the mean salaries of all the employees but not necessarily the median

Hence, the correct answer is option E.

Answer: E

IMO E
Is there a different "style" to the additional 2019 questions? I don't have the book.

Anyone else notice how many of the new quant questions are related to Medians?

Seems almost excessive.

Cheers,

We need to find the value of the median salary.

St 1: The median is the 15th salary, so we can say company has 14 + 1 + 14 = 29 employees or n = 29.
We don't get any value for the median salary - Insufficient

St 2: the sum of the annual salaries of the n employees is $913,500
No information about the median salary, as we don’t have any information about the individual salaries.

Combine, we don't get any value for the median salary. Hence OA (E)

One thing to note is that the answer would be C if the problem was changed to state "Each of the n employees at a certain company has the same annual salary."

Then, combining the statements we could find the salary since median would equal mean.

This is one of the most interesting questions. The answer could have been C if it were mentioned that either a)salary is same or b) the salary is in AP for all the employees
