2. (8 points) From 1999 to 2010, over a period of 12 years, the price increase was $150 \%$ (i.e., items that could be bought with 100 yuan in 1999 would cost 150 yuan more in 2010). If the wages of frontline employees in a certain company have not changed over these 12 years, in terms of purchasing power, this is equivalent to a wage decrease of $\qquad$ $\%$.
【Solution】Solve: $100+100 \times 150 \%$
$$
\begin{array}{l}
=100+150 \\
=250 \text { (Yuan) } \\
1-100 \div 250 \\
=1-40 \% \\
=60 \%
\end{array}
$$

Answer: In terms of purchasing power, it is equivalent to a wage decrease of $60 \%$. Therefore, the answer is: 60.
