Study the given graph and answer the question the follows.

In 2019, if the production of vehicles of type A increased by the same percentage as that in 2018, over its previous year, then what was the number(in thousands) of vehicles of type A produced in 2019?

490

Percentage increase in number of vehicles of type A in 2018 as compared to previous year

= \(\frac{420-360}{360}\) × 100

= \(\frac{60}{360}\) × 100

= 16.67%

So  number of vehicles produced in 2019 = \(\frac{7}{6}\) × 420

= 490
