Zorluk: ZorAnalytical Puzzles and Grouping

Five departmental secretaries—Anand, Bhavna, Charan, Divya, and Esha—are ranked from 1st (highest) to 5th (lowest) based on their annual performance evaluation scores. Consider the following clues:
1. Bhavna is ranked higher than Esha but lower than Anand.
2. Exactly two secretaries are ranked between Anand and Divya, with Anand holding a higher rank than Divya.
3. Charan is ranked immediately below Bhavna.
4. Divya is not ranked 5th.

Arrange the five secretaries in sequence from the highest rank (1st) to the lowest rank (5th).

  1. 1Anand
  2. 2Bhavna
  3. 3Charan
  4. 4Divya
  5. 5Esha

Cevap

The correct order of secretaries from highest rank (1st) to lowest rank (5th) is Anand, Bhavna, Charan, Divya, and Esha.
The sequence Anand -> Bhavna -> Charan -> Divya -> Esha uniquely satisfies all clues: Anand (1st) and Divya (4th) have two secretaries between them, Divya is not 5th, Bhavna (2nd) and Charan (3rd) form an immediate consecutive pair, and Esha takes 5th rank.

Adım Adım Çözüm

1
Analyze the linear separation between Anand and Divya.
Since exactly two secretaries sit between Anand and Divya with Anand having a higher rank (lower number), the possible rank pairs for (Anand, Divya) are (1, 4) or (2, 5).
Positional gap requirement of 2 intervening positions.
2
Apply the boundary constraint for Divya.
Divya cannot be ranked 5th, which eliminates the (2, 5) configuration. Therefore, Anand is ranked 1st and Divya is ranked 4th.
Explicit negative clue eliminates candidate rank pair.
3
Place the consecutive pair of Bhavna and Charan.
The unassigned ranks are 2, 3, and 5. Since Charan is immediately below Bhavna, they must take adjacent slots (2, 3), placing Bhavna at 2nd and Charan at 3rd.
Contiguous block constraint requirement.
4
Assign Esha to the remaining rank and verify all conditions.
Esha takes rank 5. This maintains Bhavna (2nd) ranked higher than Esha (5th) and lower than Anand (1st).
Deterministic completion of linear ranking.
