Sections should be considered as below

A - With more than 1 year work experience
F - Less than 1 yr work experience
B - Advanced degree with more than 1yr WE
C - Advanced degree with less than 1 yr WE
D - No advanced degree and experience more than 1 yr
E - No advance degree and experience less than 1 yr.


D = 20% and need to find out C

Statement 1
(1) 35 percent of the employees do not have advanced degrees and 55 percent have less than one year of work experience.

D+E = 35% ----(1)
F = 55% ----(2)

So A= 45% and B+C = 65%

D = 20% ----(3)

from (1) and (3)

E = 15 %
F = C+ E so C = 40% ( sufficient

Statement 2:

15 percent of the employees lack an advanced degree and have less than one year of work experience; 45 percent have one year or more of experience.

E = 15%

A = 45%

D = 20% (from question)

B = 25% as B+D = A

since A is 45 F = 55 As A+F = 100

E+C = F
so C = 40%

sufficient

so Ans = D

+1 for D. Grid method is the best possible option to opt for here. Venn diagram eats up too much of time in these sort of questions.

D it is.
For such problems, the grid method is the best way to arrange and solve. Got to the answer quickly because of the grid method. The Venn diagram method would, IMO, take a lot more than 2 minutes.
