Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 40%.
Number of serious accidents in 2016 = 50
Number of serious accidents in 2017 = 30
Reduction = 50 - 30 = 20
Percentage reduction = (20/50) × 100 = 40%
Therefore, the percentage reduction in serious accidents from the year 2016 to 2017 is 40%.
