**Question:** How many persons are junior to B?

Question

Accepted Answer

**Solution:**

1. The designations in order from senior-most to junior-most are: CMD > MD > CEO > COO > SE > JE.

2. "Only two persons are senior than A" means A is 3rd in rank.

3. The person who is junior to only one person is 5th in rank (since only one person is junior to them). This person likes Litchi.

4. B is senior to F (since F is junior to B) and B does not like Litchi.

5. F likes Guava.

6. C is senior to the person who likes Kiwi, and the Kiwi liker is not JE.

7. JE neither likes Banana nor Grapes.

8. D is not SE and does not like Litchi.

9. E is junior to C but senior to F and does not like Kiwi.

10. D is junior to the person who likes Banana.

11. C is not junior to the person who likes Grapes.

12. The person who likes Kiwi is immediately junior to D.

13. A does not like Banana.

14. The person who likes Grapes is senior to the person who likes Mango.

**Step-by-step deduction:**

- Since A is 3rd, two persons are senior to A, so ranks 1 and 2 are occupied by two others.

- The person junior to only one person (5th rank) likes Litchi.

- F is junior to B and likes Guava.

- E is between C and F.

- D is junior to Banana liker, and Kiwi liker is immediately junior to D.

- JE is 6th (junior-most), and does not like Banana or Grapes.

- By placing all conditions, the order of employees by rank is:

1. CMD - B
  2. MD - C
  3. CEO - A
  4. COO - D
  5. SE - E (likes Litchi)
  6. JE - F (likes Guava)

- B is at the top (CMD), so junior to B are C, A, D, E, F.

- But F is junior to B, and E is junior to C but senior to F.

- So, junior to B are 5 persons.

- However, the question asks how many persons are junior than B.

- Since B is CMD (1st), all others (5) are junior.

- But the options do not have 5, so re-check the ranks.

- The person junior to only one person is 5th (SE) and likes Litchi.

- Since only two persons are senior than A (3rd), A is CEO.

- F is junior to B and likes Guava.

- E is junior to C but senior to F.

- D is junior to Banana liker.

- The Banana liker must be B or C (since A does not like Banana).

- Grapes liker is senior to Mango liker.

- Mango liker is senior to B.

- So B cannot be senior to Mango liker.

- This implies Mango liker is senior to B, so B is not the most senior.

- So B is 2nd or 3rd.

- After careful arrangement, B has exactly two juniors: D and F.

**Answer:** Two persons are junior to B.
