A, B, C, D and E are in a row. A is between D and C, B is between A and C, D is between C and E. Which letter is in the middle?
Read Explanation:
E --- D --- A --- B --- C
First, we know that D is between C and E, so we have: C — D — E
Next, A is between D and C, which means we need to place A between these two letters: C — A — D — E
But this creates a contradiction because we can't have A between C and D while also having D between C and E.
The only way to satisfy all conditions is to arrange them in a line as: E — D — A — B — C
