题目问，如果麻醉师被起诉的人数是整形师的2倍，而当年10%的整形师被起诉，那么被起诉的麻醉师的百分比

anesthesiologist占3.3%
surgical一共占24%: 其中分成5部分，从那张表可以算出orthopedics占surgical的比例（12.3/5个数的和），从而可以算出orthopedics占总体的比例，就是前面那个数再乘上24%，假设这个结果为A
然后就是根据问题，anesthesiologist遭到的投诉是orthopedist的两倍，orthopedist中有10%遭到投诉
所以最后的结果就是(A*10%*2)/3.3%

orthopedists 人数是12.3*1000，被起诉数是，12.3*1000*10%=1230，则anesthesiologists被起诉人数是它的两倍2460.
anesthesiologist总人数是3.3%*421300
百分率为2460/（3.3%*421300）
