Four students are sitting on a bench to be photogrpahed. Kamal is to the left of Amrita. Dipak is to the right of Amrita. Ankit is between Amrita and Dipak. Identify students sitting in corner’s of the bench?

1. Kamal is to the left of Amrita ⇒ K is somewhere left of A.
2. Dipak is to the right of Amrita ⇒ A is left of D.
3. Ankit is between Amrita and Dipak ⇒ order among these three must be A – N – D (from left to right).
4. Now place Kamal (K) to the left of Amrita as required. With four seats, the only arrangement that satisfies all:
   K  –  A  –  N  –  D

Students at the corners: Kamal (left corner) and Dipak (right corner).
