Five boys are so standing that they form a circle. Rahim is between Ajoy and Tom. Salman is to the left of Bablu and Ajoy is to the right of Salman. Who is at the right of Bablu?

  1. A
    Tom
  2. B
    Ajoy
  3. C
    Rahim
  4. D
    Salman

Solution & Step-by-step Explanation

Let's arrange the 5 individuals—Rahim (R), Ajoy (A), Tom (T), Salman (S), and Bablu (B)—in a circle facing inward toward the center:
1. When facing the center of the circle, moving clockwise corresponds to the left side of an individual, while moving counter-clockwise corresponds to their right side.
2. Let's fix Salman at position 0.
3. We are told "Ajoy is to the right of Salman", which places Ajoy at position 1 (counter-clockwise relative to Salman).
4. "Salman is to the left of Bablu" means that if we look from Bablu's seat, Salman must be one spot clockwise. This fixes Bablu at position 4.
5. "Rahim is between Ajoy and Tom." Since Ajoy is at position 1 and position 0 is filled by Salman, Rahim must occupy position 2, leaving position 3 for Tom.

Let's check the complete circular sequence in a counter-clockwise direction:



Looking at Bablu's position (4), moving to his immediate right means moving one spot counter-clockwise, which brings us to position 3, occupied by Tom.
