Graduates got job = 32
Graduates continued to second degree = 45
Graduates got job and continued to second degree = 13
Graduates didn't get job and didn't continue to second degree = 9


Job No Job Total

Second Degree 13 32 45

No Second Degree 19 9 28

Total 32 41 X


Therefore X = 73 ..... Answer C ......


Please, consider giving kudos if you find my answer helpful in any way :) :good :thumbup:
