Question

Three automatic toys perform two types of movements: Neck Movements (NM) and Hand Rotations (HR). The data is recorded starting from 9 AM on 12 June.

  • Toy A: Battery Capacity = 1500 units, Battery Percentage = 80%. It consumes 1 unit of battery at every 4th NM and 3rd HR occurring simultaneously. Toy A completely discharges at 11 AM.

  • Toy B: Battery Capacity = 2000 units, Battery Percentage = 75%. NM rate = 30 per minute. HR rate = 50% of Toy A's NM rate. It consumes 1 unit of battery at every 3rd NM and 2nd HR occurring simultaneously.

  • Toy C: Battery Capacity = 120% of Toy B's battery capacity, Battery Percentage = 60%. NM rate = Toy A's NM rate + 5 per minute. HR rate = 30 per minute. It consumes 1 unit of battery at every 3rd NM and 2nd HR occurring simultaneously.

Question: What is the difference between the total number of Neck Movements and Hand Rotations performed by Toy C when its battery is fully discharged? (Consider the available battery percentage.)
