Nine persons work in three departments, i.e., operations, finance and marketing, of a company. On their meeting day, they wear different coloured shirts, i.e., white, blue, green, orange, red, black, purple, pink and violet. All the information is not necessarily in the same order as given. The persons in operations do not wear orange or black. T works only with the one wearing green but not in marketing. R wears white and works with G but not in marketing. Only the persons wearing red and black work together in the same department. B works with E and neither of them wears black. A does not work in operations but wears violet. M neither works in finance nor with the one wearing red. The one wearing purple does not work in finance. G and D do not wear red or orange. H does not work with E, who does not wear blue or orange. Who works in the marketing department?

D, E
H, D
M, H, E
G, B

Correct answer: H, D

Solution

The clues create a constrained grouping of people by department and shirt colour. After placing the fixed relations such as R with G, B with E, and the restrictions on operations and finance, the only consistent marketing department pair is H and D. Other options violate at least one department or colour condition.
