Show answer & explanation

Correct answer: C

Concept

These grouping puzzles are solved by fixing the smallest, most constrained facts first, then propagating each clue until every person has exactly one department and one colour. With 7 people across 3 departments and the rule that no department holds fewer than 2 or more than 3, the only possible split of group sizes is 3, 2 and 2. Build a department-vs-colour grid and eliminate impossibilities clue by clue.

Building the arrangement

  1. Fixed colours and seats: F likes Yellow, E likes Red, and G is in Finance. F and A are in different departments and neither is in HR, so F and A occupy Finance and Marketing in some order.

  2. E sits with A; B sits apart from E. Since A is in Finance or Marketing, place A and E together and keep B in a different group.

  3. The Black-liker is not in Marketing and shares a group with the Orange-liker; A and G dislike Orange. The only group that can hold both Black and Orange (size 3, not Marketing) is Finance, anchored by G.

  4. G already dislikes Orange, so within Finance G takes Black and the third Finance member takes Orange. F likes Yellow, so the Orange-liker must be B — placing B in Finance with G, and F joins them, giving Finance = three people.

  5. D shares a group with the White-liker but not with F or A, and D does not like White. That forces D into HR. C works only with the Blue-liker, so C and the Blue-liker form the 2-person HR group with D — meaning D likes Blue and C likes White.

  6. The remaining group is Marketing with A and E (E = Red), leaving A = Green.

Cross-check the statements

The question asks which statement is NOT true. Test each against the grid:

  • Blue-liker (D) is in HR — true.

  • A is in Marketing — true.

  • B is in Finance and D is in HR, so they are in different departments — this statement is false, and is therefore the answer.

  • A likes Green — true.

  • Orange-liker (B) is in Finance — true.

Only the claim that B and D share a department conflicts with the unique arrangement, so it is the statement that is not true.
