Solution :
As per the given graph:
The average number of road accidents due to buses in the years 2008, 2011, and 2013= $\frac{30+60+10}{3}=\frac{100}{3}$
The average number of road accidents due to cars in the years 2008, 2011, and 2013 = $\frac{40+20+20}{3}=\frac{80}{3}$
The required ratio = $\frac{100}{3}$:$\frac{80}{3}$
The required ratio = $5:4$
Hence, the correct answer is $5:4$.
