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?
Answer & explanation
Correct answer: option 1
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
