The given table represents the sale (in thousands) of cars by four companies A, B, C and D in six years. Study the table and answer the question that follows.

The total number of cars sold by companies A in 2017 and C in 2013 is what percentage of the total number of cars sold by all four companies in 2013 and 2016? (correct to one decimal place)

The total number of cars sold by companies A in 2017 and C in 2013 = 52 + 65 = 117

The total number of cars sold by all four companies in 2013 = 45 + 63 + 65 + 67 = 240

The total number of cars sold by all four companies in 2016 = 72 + 58 + 70 + 63 = 263

The total number of cars sold by all four companies in 2013 and 2016 = 240 + 263 = 503

Required percentage = $$\frac{117}{503} \times 100 = 23.26% ~ 23.3%
