In 2019, if the production of vehicles of type A increased by the same per cent as in 2016 over its previous year, then what was the number (in thousands) of vehicles of type A produced in 2019?

The number of cars produced by the company are as follows:

Number of Type A vehicles produced in 2015 = 200000

Number of Type A vehicles produced in 2016 = 315000

Percentage increase = $$\ \dfrac{\left(315000-200000\right)}{200000}\times100=\ \dfrac{115}{2}\%=57.5\%$$

Number of Type A vehicles produced in 2018 = 450000

Number of Type A vehicles produced in 2019 = $$450000\times\left(1+57.5\%\right)=450000\times1.575=708750$$

Total number of Type A vehicles produced in 2019 (in thousands) = 708.75

$$\therefore\ $$ The required answer is A.
