Show answer & explanation
Correct answer: A
First, sum the registered cars for all cities in 2017: 7500 + 1200 + 6000 + 5000 = 19700. Next, sum the registered cars for all cities in 2020: 9500 + 1500 + 10000 + 7400 = 28400. The ratio of total cars in 2020 to 2017 is 28400 : 19700, which simplifies to 284 : 197.
