Question 1

Five persons E, A, D, C and B are sitting in a row facing North. E sits at one of the extreme ends. A sits second to the right of E. D sits immediately to the left of A. C 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
- A sits second to the right of E → A at position 3
- D sits immediately to the left of A → D at position 2

Position: E D A _ _

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