annual salary

by vscid » Sat Dec 20, 2008 6:32 pm
Division R of company Q has 1000 employees. What is the average (arithmetic mean) annual salary of employees at company Q?

1] The average annual salary of employees in division R is 30,000.

2] The average annual salary of the employees at Company Q who are not in division R is 35,000.

-----------------------------
Please give explanations.
The GMAT is indeed adaptable. Whenever I answer RC, it proficiently 'adapts' itself to mark my 'right' answer 'wrong'.

Since no information is given about the number of people who are not in division R, we can not calculate the average of the whole company, so I rather not worry about calculations and choose E.

Stmt I is missing info on Q (other than division R)

Taken together still dont have all the info (dont know how many employees company Q has other than division R)

Choose E)
