D ?

Here is how I reached it
Given: only >=1yr experience and no advanced degree is 20%
A.
35% no advanced degree=>65% advanced degree
55%<1yr exp. => 45%>=1yr exp =>45-20=25% that is >=1yr exp and advanced degree 65-25 gives the answer.
Sufficient

B.
15 gives 85% as set of advanced degree and/or >=1yr exp. => 85-20=65% advanced degree
45%.. 100-45=55% same information as second part in A
Sufficient

I think I have misunderstood the question. Can anyone try to solve this ? What is the answer for "advanced degree and <1 year" employees?

lagomez · Answer

Since the answer is D you get the same answer for both:

Maxtrix:
Column Headings: Avanced - No Advanced - Total
Row Headings: Less than 1 - More than 1 - Total

Advanced less than 1 = 40%
Advanced more than 1 = 25%
Advanced total = 65%

No advanced less than 1 = 15%
No advanced more than 1 = 20%
No advanced total = 35%

Less than 1 total = 55%
More than 1 total = 45%
