The following table shows the cumulative number of sale of Red Electric Vehicles (EVs) out of the total number of Red and White EVs sold and the cumulative percentage of the total number of EVs sold in five different months from May to September. Based on the data in the table, answer the questions that follow.
Month-wise Sale Distribution of EVs
Months Cumulative number of sale of Red EVs Cumulative percentage of sale of EVs (Red and White in colour) May 360 25 % Till June 456 41 % Till July 816 61 % Till August 1032 79 % Till September 1232 100 %
Note: Total number of EVs (Red and White) sold in all the 5 months is 2400.
To answer the question, we need to determine the number of White EVs sold in May and the number of Red EVs sold in September. Then, we will calculate the percentage by which White EVs sold in May are more than Red EVs sold in September.
Red EVs Sold in September
The table provides cumulative sales of Red EVs. To find the sales in a specific month, we subtract the cumulative sales up to the previous month from the cumulative sales up to the current month.
- Cumulative number of sale of Red EVs till August: 1032
- Cumulative number of sale of Red EVs till September: 1232
Number of Red EVs sold in September = (Cumulative Red EVs till September) - (Cumulative Red EVs till August)
Using LaTeX: $ \text{Red EVs in Sep} = 1232 - 1032 $
Number of Red EVs sold in September = $200$.
White EVs Sold in May
The table states that the total number of EVs (Red and White) sold in all 5 months is 2400. The cumulative percentage of EVs sold till May is 25%.
This means the total number of EVs sold cumulatively up to May is 25% of the total 2400 EVs.
Total EVs sold till May = $25\% \times 2400$
Using LaTeX: $ \text{Total EVs till May} = 0.25 \times 2400 = 600 $
The cumulative number of sale of Red EVs till May is given as 360.
The number of White EVs sold cumulatively till May is the total EVs sold till May minus the cumulative Red EVs sold till May.
White EVs sold till May = (Total EVs sold till May) - (Cumulative Red EVs sold till May)
Using LaTeX: $ \text{White EVs till May} = 600 - 360 $
White EVs sold till May = $240$.
Note: Based on the common interpretation of such data tables and the provided options, "Number of White EVs sold in May" refers to the cumulative number of White EVs sold by the end of May.
Percentage Difference Calculation
We need to find by what percentage the number of White EVs sold in May (240) is more than the number of Red EVs sold in September (200).
Difference = (White EVs sold in May) - (Red EVs sold in September)
Using LaTeX: $ \text{Difference} = 240 - 200 = 40 $
To calculate the percentage more, we use the formula:
Percentage More = $ \left( \frac{\text{Difference}}{\text{Number of Red EVs sold in September}} \right) \times 100 $
Percentage More = $ \left( \frac{40}{200} \right) \times 100 $
Percentage More = $ \frac{1}{5} \times 100 $
Percentage More = $20\%$.
Therefore, the number of White EVs sold in May is 20% more than the number of Red EVs sold in September.
