Correct Answer: 332.(3)
Solution: (3) For the year 2010 ,
$\frac{2-E_{1}}{E_{1}}=\frac{1}{2}$
$\Rightarrow 4-2 E_{1}=E_{1}$
$\Rightarrow 3 E_{1}=4$
$\Rightarrow E_{1}=\frac{4}{3}$
For the year 2011,
$\frac{3-E_{2}}{E_{2}}=\frac{45}{100}=\frac{9}{20}$
$\Rightarrow 60-20 E_{2}=9 E_{2}$
$\Rightarrow 29 E_{2}=60$
$\Rightarrow E_{2}=\frac{60}{29}$
$\therefore E_{1}: E_{2}=\frac{4}{3}: \frac{60}{29}$
$=\frac{1}{3}: \frac{15}{29}=29: 45$
