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) sale is 80% or more but less than 90% of the production?

2015, 2019

Percentage of sale for 2015 =  \(\frac{1000}{1250}\) × 100 = 80%

Percentage of sale for 2016 = \(\frac{1290}{1400}\) × 100 = 92.14%

Percentage of sale for 2017 = \(\frac{1100}{1450}\) × 100 = 75.86%

Percentage of sale for 2018 = \(\frac{1450}{1500}\) × 100 = 96.67%

Percentage of sale for 2019 = \(\frac{1390}{1600}\) × 100 = 86.87%

So , Sale in 2015 & 2019 is 80% or more but less than 90% .
