The following bar graph shows the number of accidents that happened in a city during the year 2021.
B = difference in accidents of two wheelers and buses. B is what percent of total number of accidents?

Answer & explanation
Correct answer: option 2
According to the bar graph,
Number of accidents in two wheelers = 330
Number of accidents in buses = 180
Their difference = 150
Total number of accidents in 2021 = 220 + 180 + 200 + 330 + 70
= 1000
Required percentage = $\frac{150}{1000}$ x 100 = 15%
