According to given bar graph , we have
Total number of accidents = 25 + 19 + 30 + 43 + 35 + 27 = 179
Number of months = 6Average Number of accidents = Total number of accidents = 29.83 Number of months Average Number of accidents = 179 = 29.83 6
Number of accidents in April = 43Correct Option: A
According to given bar graph , we have
Total number of accidents = 25 + 19 + 30 + 43 + 35 + 27 = 179
Number of months = 6Average Number of accidents = Total number of accidents = 29.83 Number of months Average Number of accidents = 179 = 29.83 6
Number of accidents in April = 43
∴ Required answer = 43 – 29.83 = 13.17
