I want to know the answer to the following question:
Between 2010 and 2012, by what percentage were the wages of public servants cut?
All the background I'm provided with is that "In 2012, all public servants had already seen an average wage cut of 20% relative to their 2010 baseline, with cuts reaching 25% for those earning more than 1,500 euro per month.". Is that enough to answer the question?
