The following table shows the details about the number of different categories of vehicles sold (in thousands) in a city over the years 2017 - 2021. Based on the data in the table, answer the question: Year - wise Sale of Vehicles (in thousands) Year Vechile Category HCV LCV Car Jeep Two - Wheeler 2017 52 128 464 306 680 2018 90 120 484 344 672 2019 144 158 496 420 808 2020 162 186 560 482 822 2021 214 224 532 470 884 HCV : Heavy Commercial Vehicle : LCV : Light Commercial Vehicle
If the percentage increase in the sale of HCVs in 2022 over 2021 is expected to be same as in 2021 over 2020. then approximately how many HCVs (in thousands) will be sold in 2022?
The question asks us to predict the number of Heavy Commercial Vehicles (HCVs) expected to be sold in 2022. The prediction is based on the assumption that the percentage increase in HCV sales from 2021 to 2022 will be the same as the percentage increase observed from 2020 to 2021. We need to use the provided table data to perform this calculation.
First, let's look at the sales data for HCVs in the years 2020 and 2021 from the given table:
| Year | Vehicle Category | HCV |
|---|---|---|
| 2020 | 162 | |
| 2021 | 214 |
The sales figures are in thousands.
To find the percentage increase, we first calculate the absolute increase in sales from 2020 to 2021.
Increase in sales = Sales in 2021 - Sales in 2020
\(\text{Increase} = 214 - 162 = 52 \text{ thousand}\)
Now, we calculate the percentage increase relative to the sales in the starting year (2020):
\(\text{Percentage Increase} = \left( \frac{\text{Increase}}{\text{Sales in 2020}} \right) \times 100\)
\(\text{Percentage Increase} = \left( \frac{52}{162} \right) \times 100\)
\(\text{Percentage Increase} = \left( \frac{26}{81} \right) \times 100\)
The question states that the percentage increase in the sale of HCVs in 2022 over 2021 is expected to be the same as the percentage increase in 2021 over 2020.
Let \(S_{2022}\) be the expected HCV sales in 2022.
The increase from 2021 to 2022 will be \(S_{2022} - 214\).
The percentage increase from 2021 to 2022 is \(\left( \frac{S_{2022} - 214}{214} \right) \times 100\).
Setting the percentage increases equal:
\(\left( \frac{S_{2022} - 214}{214} \right) \times 100 = \left( \frac{52}{162} \right) \times 100\)
We can cancel out the 100 from both sides:
\(\frac{S_{2022} - 214}{214} = \frac{52}{162}\)
Now, solve for \(S_{2022}\):
\(S_{2022} - 214 = 214 \times \frac{52}{162}\)
\(S_{2022} - 214 = 214 \times \frac{26}{81}\)
\(S_{2022} = 214 + 214 \times \frac{26}{81}\)
\(S_{2022} = 214 \times \left( 1 + \frac{26}{81} \right)\)
\(S_{2022} = 214 \times \left( \frac{81+26}{81} \right)\)
\(S_{2022} = 214 \times \frac{107}{81}\)
Calculating the value:
\(S_{2022} = \frac{214 \times 107}{81} = \frac{22900}{81}\)
\(S_{2022} \approx 282.716\)
The question asks for the approximate number of HCVs (in thousands) that will be sold in 2022. Our calculated value is approximately 282.716 thousand. Looking at the options, the closest value to 282.716 is 282.
Therefore, approximately 282 thousand HCVs will be sold in 2022.

| Data Extraction | Identifying specific values from a table. | Gathering HCV sales data for 2020 and 2021. |
| Forecasting | Predicting future values based on historical trends. | Predicting 2022 sales based on 2020-2021 growth rate. |

The table categorizes vehicles into HCV, LCV, Car, Jeep, and Two-Wheeler. Each category represents different market segments and might show different growth trends over time. Understanding these categories helps in analyzing the overall health of the automobile industry and predicting future demand.
Analyzing year-on-year percentage changes for each category provides insights into which segments are growing or declining. Consistent growth rates, as assumed for HCVs in this problem, are often used as a simple forecasting method, though real-world predictions use more complex models considering various economic factors.
