Study the given graph and answer the question that follows.

In which year was the percentage increase in the revenue as compared to that in its preceding year below 6% ?

2017

Lets solve one by one for each option ,

1. 2015

Percentage increase in the revenue as compared to previous year

= \(\frac{350 - 320  }{320}\) × 100

= = \(\frac{30 }{320}\) × 100

= 9.375%

2. 2019

Percentage increase in the revenue as compared to previous year

= \(\frac{300 - 280  }{280}\) × 100

= \(\frac{20 }{280}\) × 100

= 7.14%

3. 2016

Percentage increase in the revenue as compared to previous year

= \(\frac{380 - 350  }{350}\) × 100

= \(\frac{30 }{350}\) × 100

= 8.57%

4. 2017

Percentage increase in the revenue as compared to previous year

= \(\frac{400- 380  }{380}\) × 100

= = \(\frac{20 }{380}\) × 100

= 5.26%

which is approximately equal to 6%
