Comment on Gigacorp Managers
Tricky I would have chosen 60
Agreed!
Agreed!
Why dint we do 60/250 ?
Great question!
Great question!
If you feel the answer is 60/250, then you are answering a different question from the one that is asked.
Among the 250 managers at Gigacorp, 60 are females with MBAs.
so, IF the question were "What percent of ALL MANAGERS are females with MBAs?", then the correct answer would be 60/250
However, the question actually asks "What percent of the FEMALE MANAGERS have MBAs?"
There are 150 FEMALE MANAGERS
Among those 150 FEMALE MANAGERS, 60 have MBAs
60/150 = 40%
Does that help?
