Explanation
The correct answer is option 4 i.e. 220%.
Production of cement by company X in 2020 = 30 lakh tonne
Production of cement by company Z in 2022 = 25 lakh tonne
Production of cement by company X in 2020 and production of cement by company Z in 2022 together = 55 lakh tonne
Production by company W in 2021 = 25 lakh tonne.
