Three automatic toys A, B, and C operate with different battery capacities and consumption patterns based on neck movements (NM) and hand rotations (HR).

• Toy A: Battery capacity = 1500 units, initially charged to 80%. It consumes 1 unit of battery at every 4th NM and 3rd HR together. It gets fully discharged at 11 AM starting from 9 AM.
• Toy B: Battery capacity = 2000 units, initially charged to 75%. It performs 30 NM per minute, and HR per minute is 50% of Toy A's NM per minute. It consumes 1 unit of battery at every 3rd NM and 2nd HR together.

If both Toy A and Toy B were fully charged to 100%, what would be the difference in their total operating times until complete discharge?
