Study the following mixed graph carefully and answer the questions that follow. The graph illustrates the number of electric cars manufactured by a company over five years and the percentage exported each year. Cars not exported were sold within the country. | Year | Cars manufactured (in thousands) | Exported | |---|---:|---:| | 2020 | 80 | 25% | | 2021 | 100 | 30% | | 2022 | 120 | 35% | | 2023 | 150 | 40% | | 2024 | 180 | 45% |

Find the ratio of the total number of cars exported in 2020 and 2021 together to the total number of cars manufactured in 2024.

5:8

9:20

7:23

5:18

✅ Correct Option: 4

Exported cars in 2020 $=25\%$ of $80,000=20,000$. Exported cars in 2021 $=30\%$ of $100,000=30,000$. Total exported in 2020 and 2021 $=20,000+30,000=50,000$. Cars manufactured in 2024 $=180,000$. Required ratio $=50,000:180,000=5:18$.

Question 6

Find the percentage by which the total number of cars sold within the country in 2022 and 2023 together exceeds the total number of cars sold within the country in 2020 and 2024 together. (Round off your answer to two decimal places.)
