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.
August Red EV Sales Calculation
The question asks us to find the specific number of Red Electric Vehicles (EVs) that were sold during the month of August. The provided table gives us cumulative sales data, meaning the total sales from the beginning up to a certain point in time, rather than sales for that specific month alone. To determine the sales for August, we need to use the cumulative figures provided for August and the preceding month, July.
Determining August Sales Figures
We need to extract the relevant cumulative sales data for Red EVs from the table:
- Cumulative number of Red EVs sold till August: 1032
- Cumulative number of Red EVs sold till July: 816
To calculate the number of Red EVs sold specifically in August, we subtract the cumulative sales up to July from the cumulative sales up to August. This difference represents the sales that occurred only within the month of August.
The calculation is performed as follows:
Number of Red EVs sold in August = (Cumulative Red EVs sold till August) - (Cumulative Red EVs sold till July)
Using LaTeX for the mathematical expression:
Number of Red EVs sold in August = $1032 - 816$
Performing the subtraction:
$1032 - 816 = 216$
Therefore, 216 Red EVs were sold in August. This matches option 4.
