Q: A, B, C, D, and E are five siblings. A is older than B but younger than C. D is younger than E. If C is the oldest, who is the youngest? (2023)

Solution: Since D is younger than E and A is older than B, D must be the youngest.

Steps: 8

Step 1: Identify the relationships between the siblings based on the information given.
Step 2: A is older than B but younger than C, which means C > A > B.
Step 3: Since C is the oldest, we know C is the oldest sibling.
Step 4: D is younger than E, which means E > D.
Step 5: We need to find out who is the youngest among A, B, D, and E.
Step 6: Since A is older than B, B is younger than A.
Step 7: We have established that C is the oldest, and A is older than B.
Step 8: Since D is younger than E, and we have no information that places D older than B, D must be the youngest.
