Question

The number of Deaths due to Car accidents is what percent of the total number of accidents due to Cars?

• A. $20$
• B. $41.5$
• C. $28$
• D. $37.5$

Answer 1

Answer: (D)

$37.5$

Total number of accidents due to various vehicles $=48000$

Percentage of accidents by car $=15\%$

Ratio of death to injuries by car $3:5$

Number of deaths due to car accidents $=48000\times \frac{15}{100}\times \frac{3}{8}=2700$

Total number of accidents due to cars $=48000\times \frac{15}{100}=7200$

$\therefore$ Required percentage $=\frac{\text{Number of deaths due to car accidents}}{\text{Total number of accidents due to cars}}\times 100=\frac{2700}{7200}\times 100=37.5\%$

Hence $\text{D}$ is the correct option.
