Four of the following five are alike in a certain way and thus form a group. Who among the following doesn’t belong to the group?

Accepted Answer

**Solution:**

1. From the given data, the qualifications are either HR or Diploma.

2. The options show persons with their qualifications:
   - A - HR
   - B - Diploma
   - D - HR
   - F - Diploma
   - H - Diploma

3. We need to find who does not belong to the group formed by the other four.

4. Observing the qualifications:
   - A, D have HR qualification.
   - B, F, H have Diploma qualification.

5. The question states "Four of the following five are alike in a certain way and thus form a group."

6. From the passage, A and D have the same qualification (HR), and B, F, H have the same qualification (Diploma).

7. So the groupings are:
   - Group 1: A (HR), D (HR)
   - Group 2: B (Diploma), F (Diploma), H (Diploma)

8. Since four form a group, the group must be the larger group of Diploma holders (B, F, H) plus one more.

9. But there are only three Diploma holders listed here (B, F, H).

10. The other two are HR (A, D).

11. So the group of four must be those who share the same department or qualification.

12. From the passage, E, G, H have the same qualification but different from B. B doesn’t have HR qualification.

13. Since B is Diploma and E, G, H have the same qualification different from B, E, G, H must be HR.

14. But from the options, H is Diploma, so this contradicts.

15. Another approach is to check the department:
    - A and D work in the same department.
    - B works in a different department.
    - C and F work in the same department but different from A's.
    - E and H work in the same department.

16. So grouping by department:
    - Dept 1: A, D
    - Dept 2: B
    - Dept 3: C, F
    - Dept 4: E, H

17. Since B is alone in his department, B doesn’t belong to any group of four.

18. Hence, B (Diploma) is the one who does not belong to the group formed by the other four.

**Answer:** (b) B - Diploma
