Year	Gross Turnover
2016	12
2017	18
2018	25
2019	25
2020	30

By what percentage is the gross turnover of 2020 higher than the gross turnover of 2018?

Correct option is A

Given:
The gross turnover of the company over the years is given in the table:
Formula Used:
Percentage Increase = $$\frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100$$​​
Solution:
The gross turnover of 2020 is 30 crores, and the gross turnover of 2018 is 25 crores.

Percentage Increase = $$\frac{30 - 25}{25} \times 100\% = \frac{5}{25} \times 100\% = 20\%$$​

The gross turnover of 2020 is 20% higher than the gross turnover of 2018.

Thus, the correct option is (a) 20%
