What is the difference between total NM andHR of toy C when the battery of toy C gets completely dis...........

Quantitative Aptitude(IBPS PO) Case Studies

Directions : Given data is regarding three automatic toys on two types of movements: Neck movements (NM) and Hand rotation (HR). It starts recording from 9 AM onwards on 12 June. Each toy has different battery percentage and battery capacity.

Toy A: Battery Capacity = 1500 units, Battery Percent = 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 percent = 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 battery capacity of toy B, Battery Percent = 60%

B, Battery Percent = 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.

What is the difference between total NM andHR of toy C when the battery of toy C gets completely discharged? (consider available battery percent)

Explanation:

Here’s what’s going on with Toy C and why only one of those options fits:

- Toy C’s battery capacity is 120% of Toy B’s: that’s 2000 units × 1.2 = 2400 units.

- The available battery is 60% of 2400, so 0.6 × 2400 = 1440 units.

- Every unit of battery for Toy C gets drained at the rate of every 3rd NM and 2nd HR combined (just like Toy B).

- To use up those 1440 battery units, Toy C will run through a set of movements:

- Toy C’s NM/min = Toy A’s NM/min + 5.

- But, for total counts, what matters is the battery and how the consumption works per unit.

- Total NM and HR moves together during the full discharge will be:

- In the cycle (3 NM + 2 HR = 1 unit consumed): 1440 cycles mean 4320 NMs and 2880 HRs.

- The difference is 4320 - 2880 = 1440.

Option 2, 1440, is the only one that comes from calculating the per-cycle movement against available charge.

Option: 2, 1440 is correct.

Everything else—1620, 1920, 1200, 1280—doesn’t fit the math from actual consumption per cycle ratios. This isn’t just about how fast Toy C moves, but about how its battery gets spent against those ratios. So, if you worked it out and got 1440 as the difference, you nailed it.
