In the table, production and sale (in 1000 tonnes) of a certain product of a company over 5 years is given. Study the table and answer the question:

In which year(s) the sale increases by more than 25% of the previous year?

2016 and 2018

Increase  in sale in 2016 = \(\frac{290}{1000}\) × 100 = 29%

Increase  in sale in 2017 = \(\frac{-190}{1290}\) × 100 = - 14.72 %

Increase  in sale in 2018 = \(\frac{350}{1100}\) × 100 = 31.81%

Increase  in sale in 2019 = \(\frac{60}{1450}\) × 100 = 4.13%

Ans :- 2016 and 2018
