The following line graph shows the production of engines (in lakh units) of various automobiles for two companies X and Y over 5 years (from 2014 to 2018). Answer the given question based on the line graph. 

For company Y, what is the approximate percentage increase in the production of engines from 2015 to 2017?

Correct option is D

Solution:

For company Y,

Production of engines in 2015 = 10,00,000

Production of engines in 2017 = 15,00,000

Production increase from 2015 to 2017 =  15,00,000 - 10,00,000

Production increase from 2015 to 2017 =  5,00,000

Percentage increase = $$\frac{5,00,000}{10,00,000}\times100$$

Percentage increase = 50%

Hence, option (d) is correct.
