90% of the total number of vehicles of type A produced in 2013, 2015 and 2016 is equal to the total number of vehicles of type B produced in the years ______.

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

Total number of Type A vehicles produced in 2013, 2015 and 2016 = (185000 + 200000 + 315000) = 700000

90% of the total number of Type A vehicles produced = 700000 $$\times\ $$ 0.9 = 630000

Total number of Type B vehicles produced in 2014 and 2017 = (280000 + 270000) = 555000

Total number of Type B vehicles produced in 2015 and 2018 = (225000 + 350000) = 575000

Total number of Type B vehicles produced in 2015 and 2017 = (225000 + 270000) = 495000

Total number of Type B vehicles produced in 2014 and 2018 = (280000 + 350000) = 630000

Hence, Total number of Type A vehicles produced in 2013, 2015 and 2016 is equal to the total number of Type B vehicles produced in 2014 and 2018. 

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