Given the rationale, provide a reasonable question and answer. Step-by-step reasoning process: First find Bill's height by dividing Cary's height by 2: 72 inches / 2 = 36 inches. Then add six inches to find Jan's height: 36 inches + 6 inches = 42 inches.
The question and answer:
Cary is 72 inches tall. Her younger brother Bill is half her height, and her younger sister Jan is 6 inches taller than Bill. How tall is Jan?
The answer is 42
