Seven children A, B, C, D, E, F and G are standing in a row. G is to the right of D and immediately to the left of B. A is to the right of C. There is one child between A and D. F is second to the right of G. There are two children between D and F. Who is in the exact middle?
D
D is correct.
Number the places 1 to 7 from left to right; the middle place is 4. Let D stand at place \(x\).
Two children stand between D and F, and G is to the right of D, so F is at \(x+3\). F is second to the right of G, so G is at \(x+1\). B is immediately to the right of G, so B is at \(x+2\). This gives the block D, G, B, F in four consecutive places.
One child stands between A and D. Place \(x+2\) is taken by B, so A is at \(x-2\). A is to the right of C, so A cannot be at place 1, which means \(x-2 \ge 2\), i.e. \(x \ge 4\). The block must also fit in the row: \(x+3 \le 7\), i.e. \(x \le 4\). So \(x = 4\).
Then D = 4, G = 5, B = 6, F = 7, A = 2, C = 1 (left of A) and E takes the remaining place 3.
| Position | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Child | C | A | E | D | G | B | F |
Every clue checks out, and the child in the exact middle (place 4) is D.
