Average salary for attorneys = $75,000
Average salary for paralegals = $50,000
Average salary for all employees = $45,000
The average salary for all employees is less than the average salary of either attorneys or paralegals. This serves to prove that there is at least one employee who earns less than $[color=#ed1c24]45,000 who is not an attorney or a paralegal but is part of the firm[/color]. This is because no matter what the number of attorneys or paralegals or their earnings, their average cannot be less than $50,000.
A), B), C), and E) cannot be properly drawn, because they do not lead to an overall average salary of $45,000 by any means. D) can be drawn, as it paraphrases exactly what we concluded above.
D) it is.
Hi Gyanone,
I noted one thing in your explanation marked in green ,however (D) says :
There was at least one Legal Services, LLC employee who earned l
ess than the average paralegal earned last year.Plz explain !!!
Although the best answer is (D),consider the below equations
Number of Attorneys : x their Average = 75, their sum = 75x
Number of paralegals : y their Average = 50, their sum = 50y
Some other person in firm: 1 , Salary =46
Total average = 45
(75x + 50y +46)/(x+y+1) = 45
75x + 50y +46= 45x + 45y + 45
30x + 5y = -1 ????? A -ve value .
Had it been in (D) as marked in green the person's salary would have been less than firm's average.
Your say?
