Kevin             r-9
Robert            r
SUM              37

3r-22=37
3r=59

Bad data -- no integer solution.

Robert: x (oldest)
Kevin: x-9 (9 years younger than Robert)
Monica: x-13 (4 years younger than Kevin)

x%2B%28x-9%29%2B%28x-13%29+=+37
3x-22+=+37
3x+=+59

x = 19 2/3

Therefore,  from the traditional point of view,  it is  FAULT,  or DEFECTIVE,  problem.
