0%
$$499$$
0%
$$397$$
0%
$$228$$
0%
$$497$$
Explanation
Total number of people died $$=5700$$
People who were on four wheelers $$=4$$ percent
So number of people killed who were on four wheeles $$=5700\times \dfrac { 4 }{ 100 } =228$$
So option $$C$$ is correct.
The pie chart shows the road accident death by various modes in India in the year $$2012$$ .What angle is subtended by deaths due to two wheeler on the pie chart.

$${80}^{\circ}$$
0%
$${82.8}^{\circ}$$
0%
$${84.2}^{\circ}$$
0%
$${86.3}^{\circ}$$
Explanation
Totals deaths due to two wheeler $$=23$$ percent
Total angle subtended on pie chart $$={360}^{\circ}$$
Let $$\theta $$ be the angle subtended by deaths due to two wheeler accidents.
$$\theta =\dfrac { 23 }{ 100 } \times { 360 }^{ \circ }={ 82.8 }^{ \circ }$$
So option $$B$$ is correct.

Report Question
0%
$$700$$ kilogram
0%
$$800$$ kilogram
0%
$$900$$ kilogram
0%
$$950$$ kilogram
Explanation
$$\Rightarrow$$ Total number of grains Ajaybhai bought from market $$=3600\,kg$$
$$\Rightarrow$$ Percentage of Castor-seeds Ajaybhai bought from market $$=25\%$$.
$$\Rightarrow$$ Castor-seeds Ajaybhai bought from market in kilogram $$=\dfrac{25}{100}\times 3600=900\,kg$$

$$Total$$
$$50$$
$$\Rightarrow$$ Total runs scored in $$5$$ overs $$=50$$
$$\Rightarrow$$
$$\%$$ of runs scored in first over $$=\dfrac{6}{50}\times 100=12\% $$
$$\Rightarrow$$
$$\%$$ of runs scored in second over $$=\dfrac{0}{50}\times 100=0\% $$
$$\Rightarrow$$ $$\%$$ of runs scored in third over $$=\dfrac{12}{50}\times 100=24\% $$
$$\Rightarrow$$ $$\%$$ of runs scored in fourth over $$=\dfrac{14}{50}\times 100=28\% $$
$$\therefore$$ $$28\%$$ of runs scored in $$Fourth$$ over.
