Five people A, B, C, D and E sit in a row facing north. C sits exactly in the middle. A sits at one of the ends with B immediately to A's right. D does not sit at an end. How many people sit between B and E?

Explanation

1. 01

   B is to A's right, so A must be at the left end (at the right end there is no seat to A's right). B is second.

2. 02

   C is third. D is not at an end, so D is fourth and E is at the right end.

3. 03

   Row: A, B, C, D, E. Between B (second) and E (fifth) sit C and D: 2 people.
