Question 1

Five persons E, D, A, B and C are sitting in a row facing North. E sits at one of the extreme ends. D sits second to the right of E. A sits immediately to the left of D. B is not at any extreme end. Who sits at the other extreme end?
Solution Approach:

Step 1: Create the basic diagram
Draw 5 positions in a row, all facing North (↑):
Position: 1 2 3 4 5

Step 2: Apply direct conditions
- E sits at one extreme end → Place E at position 1
- D sits second to the right of E → D at position 3
- A sits immediately to the left of D → A at position 2

Position: E A D _ _

Step 3: Apply constraint conditions
- B is not at any extreme end → remaining positions are 4 and 5; B cannot be at 5, so B at position 4
- Only C remains → C at position 5

Final Arrangement (all facing North ↑):
Position: E A D B C

Verification:
✓ E at extreme end (pos 1)
