Answer is E. Here is how:
The quickest way is to setup a matrix and work through the given values in the question.

For all such problems, set up a matrix with number of columns and rows corresponding to the divisions mentioned in the question stem.

30-3=27 you have to deal with.
27=14+18-common to both the groups
hence common =5

Use Venn diagram to solve this problem. It is straight fwd.
Let
A: no. of applicants with atleast 4 years of exp.
B: no. of applicants with a degree.
C: no. of applicants with less than 4 yrs of exp.

Since we cannot have applicants with atleast 4 yrs of exp and less than 4 yrs of exp. at the same time, it is clear that intersection of A, B and C is zero. And so is with the case of intersection of A and C.

Now you can easily solve the equation of three sets.

The correct answer is 5.
