Direcions: A battery manufacturer manufactures five different types of batteries. The total revenue for the year 2020 is ₹25,00,000 and 20,000 units were exported in 2020. The distribution of revenue and units for the five different types of batteries is shown in the charts.
Which type of battery provides the lowest revenue per unit?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Lead acid.
The total revenue for the year 2020 = ₹25,00,000 and
20,000 units were exported in 2020
Here,
Revenue = Total revenue from all types of battery/Total units sold of that type
Now, from the given pie-chart
For Li- ion:
Units sold: 30% of 20000 = 6000
Revenue = 35% of 2500000 = 8750000
Revenue per unit = 8750000/6000 = 145.83 units
For Sodium:
Units sold: 2% of 20000 = 400
Revenue = 5% of 2500000 = 125000
Revenue per unit = 125000/400 = 312.5 units
For M-air:
Units sold: 20% of 20000 = 4000
Revenue = 20% of 2500000 = 500000
Revenue per unit = 500000/4000 = 125 units
For lead acid:
Units sold: 35% of 20000 = 7000
Revenue = 25% of 2500000 = 625000
Revenue per unit = 625000/7000 = 89.23 units
For S - capacitor:
Units sold: 13% of 20000 = 26000
Revenue = 15% of 2500000 = 375000
Revenue per unit = 375000/2600 = 144.42 units
Hence,
Lead acid provides lowest revenue
