Question: In which of the department, does a group of 3 work?
Explanation:
There are seven people in three different departments, such that there are atleast two people per department. Hence, the department-level breakup of people is (3, 2, 2) in any order.
There are three females such that there is one female in each department. Hence, the male-female breakup per department is: (f + m), (f + m), (f + 2m).
F is in Administration and his only colleague is G.
Hence, F = Administration = Male
Also, there are only two people in Administration i.e. F and G, one of whom has to be female.
Hence, G = Administration = Female C = Finance
A is the husband of H and works in Finance. Hence, A = Finance = Male
Since B and E are brothers, both are male and both work in different departments.
Hence, B/E = Finance = Male
Hence, the third person in Finance i.e. C, has to be female. Hence, C = Finance= Female
Since there have to be atleast two people in each department, the two remaining people have to be in Logistics i.e. E/B = Logistics = Male and H = Logistics = Female
Thus, a group of 3 works in Finance.
Hence, option (d).
Note:
The correct answer is not given in any of the options. Hence, you can mark the closest possible answer i.e. option 4.
