Question

An employer interviews 100 qualified applicants, 60 White and 40 Black. If 30 whites are hired, what is the least number of Blacks that should be hired to avoid charges of adverse impact?

Answer 1

20

 

One way to view the problem is:

 

60% of the applicants are white.  

X is the number hired.

 

 60% of X = 30

  X = 30*100/60 = 50 were hired

 

50-30 = 20

------------------------

Another way to view the problem is

that the ratio is 60/40 = 3/2 = 30/X

 

X=20
