Given the data regarding three automatic toys on two types of movements: Neck movements (NM) and Hand rotations (HR), answer the following. Toy A: Battery capacity = 1500 units, battery percentage = 80%. At every 4th NM and 3rd HR together, 1 unit of battery is consumed. Toy A gets completely discharged at 11 AM. Toy B: Battery capacity = 2000 units, battery percentage = 75%. NM = 30/min, HR/min = 50% of NM/min of Toy A. At every 3rd NM and 2nd HR together, 1 unit of battery is consumed. Toy C: Battery capacity = 120% of the battery capacity of Toy B, battery percentage = 60%. NM/min = NM/min of Toy A + 5, HR = 30/min. At every 3rd NM and 2nd HR together, 1 unit of battery is consumed. If power consumed per NM of Toy B is 0.1 unit, then what is the power consumed per HR of Toy B on that day?
- 0.45 unit
- 0.35 unit
- 0.15 unit
- 0.2 unit
Correct answer: 0.2 unit
Solution
For Toy B, the number of hand rotations per minute is 50% of Toy A's NM rate, so the movement counts are linked. Given the power consumed per NM is 0.1 unit and the total consumption pattern is fixed, the corresponding power per HR comes out to 0.2 unit.

- Direction (97-102): Read the table carefully and answer the following questions. The data shows the volume and height of 4 right circular tanks P, Q, R and S. The data also depicts the time taken to fill or empty the tank by inlet pipes A and B and outlet pipe C. 1. The ratio between the time taken by pipe B and that by pipe C is different because the pipes were used by the operator in different ways for different tanks. 2. The radius of tank S is 10.5 m. Table: Tank | Volume | Height | Time taken by pipe A to fill tank (in hours) | Ratio of time taken by pipe B to fill and pipe C to empty the tank P | 38808 | 28 | 10 | 2:3 Q | ------- | 10 | 12 | 3:2 R | 5390 | 35 | 18 | 1:3 S | 19250 | ------- | ------- | 2:5 How much volume (approximately) of initially empty tank P was filled in 1 hour, when all 3 pipes were opened simultaneously?

- Three automatic toys A, B, and C operate with neck movements (NM) and hand rotations (HR). The data are as follows: Toy A: Battery capacity = 1500 units, battery percentage = 80%. At every 4th NM and 3rd HR together, 1 unit of battery is consumed. Toy A gets completely discharged at 11 AM. Toy B: Battery capacity = 2000 units, battery percentage = 75%. NM = 30/min, HR = 50% of the NM/min of Toy A. At every 3rd NM and 2nd HR together, 1 unit of battery is consumed. Toy C: Battery capacity = 120% of the battery capacity of Toy B, battery percentage = 60%. NM/min = NM/min of Toy A + 5, HR/min = 30. At every 3rd NM and 2nd HR together, 1 unit of battery is consumed. What is the difference between the total NM and HR of Toy C when its battery gets completely discharged?
