How many of the 42 people in a group are employed students?
(1) 29 of the 42 people are employed.
(2) 24 of the 42 people are students.
The OA is E.
The answer is straight E. Even when taken together we have:
{Total} = {Students} + {Employed} - {Both} + {Neither} --> we want to calculate: {Both}, # of employed students.
{42} = {24} + {29} - {Both} + {Neither} --> {Both} = 11 + {Neither}, since we don't know # of people who are neither employed nor students, we can not answer the question.
Has anyone another strategic approach to solving this DS question? Regards!
