Approximately what percent of the faculty in humanities are non-adjunct faculty?
A. 35%
B. 38%
C. 41%
D. 45%
E. 51%

The answer would be 14% for what question like if a box would be given instead of MCQs I would have put 14%?


In 2008 the value of exports was approximately what percent greater than the value of imports?
A 40%
B 60%
C 70%
D 120%
E 140%

I followed the soln but why is the denominator Imports

If it were discovered that the value of imports shown for 2007 was incorrect and should have been $5 billion instead, then the average (arithmetic mean) value of imports per year for the 10 years shown would have been approximately how much less?
A $200 million
B $50 million
C $20 million
D $7 million
E $5 million

For this question should I recalculate but that would be time consuming right?

“Approximately what percent of the faculty are humanities and also non-adjunct faculty?”

Because you’re trying to find out how much better exports when comparing to imports.

No. You are changing the imports from $7 billion to $5 billion, that is, a change of $2 billion. The change in the mean is $2 billion/10 = $200 million, given that nothing else is being changed.
