Question
In 2020, what is the ratio of the total number of cars
produced by Company P and Company R combined to the total number of cars exported by Company Q ? Direction: The bar graph shows the Production of Cars (in thousands) for four companies (P, Q, R, S) over five years (2018 to 2022). Table: The table shows the Percentage of Exported Cars for the same four companies over the same five years.Solution
Total production by Company P and R in 2020: Company P: 85,000 Company R: 90,000 Total = 85,000 + 90,000 = 175,000 cars. Total exported cars by Company Q in 2020: 60% of 70,000 = 0.60 × 70,000 = 42,000 cars. Ratio = 175,000 : 42,000 = 175:42 = 25:6.
