#greprepclub If the number of senior managers increased by 60 percent from 1980 to 2007.jpg
Which of the following statements can be inferred from the charts above?
Indicate
all such statements.
\(\square\) From 1990 to 2000, the average salary, in actual-year dollars, increased by more than 10%.
\(\square\) In 1960, there were fewer than 5 senior managers.
\(\square\) For the decades shown, the number of senior managers increased by the greatest percentage between 1980 and 1990.
Kudos for the right answer and explanation
(C) This cannot be inferred; Even though there is a slight slump (in terms of 1950 dollars) from the decade 1980 to 1990 as per the bar graph shown, it is not enough to conclude this. If the average salary in 1980 was let's say 90K among 5 managers, 1990 could have 108K among 6 managers, and 2000 could have 180K with 10 managers, the above graph would still be plotted correctly with this info. This statement can not be inferred from the information given.
B) This statement also cannot be inferred just like (C) above. In 1960, there could be 20 managers with each have a salary of 19K and still, the graph would be drawn correctly.
A) In 1990, average salary = 80K, 2000 = 100K (est. actual value is more than this)
10% increase = 80 + (80 * 10)/100 = 88K < 100K
Hence, only A is correct.
