    题型：数学计算
    解:
          ((26%-22.45%)*2×10%+(11%-22.45%)*2×10%+(15%-22.45%)*2×20%+(27%-22.45%)*2×25%+(21%-22.45%)*2×20%+(32%-22.45%)*2×15%)*1/2
        =(0.0355*2×10%+(11%-22.45%)*2×10%+(15%-22.45%)*2×20%+(27%-22.45%)*2×25%+(21%-22.45%)*2×20%+(32%-22.45%)*2×15%)*1/2
        =(0.0355*2×10%+(-0.1145)*2×10%+(15%-22.45%)*2×20%+(27%-22.45%)*2×25%+(21%-22.45%)*2×20%+(32%-22.45%)*2×15%)*1/2
        =(0.0355*2×10%+(-0.1145)*2×10%+(-0.0745)*2×20%+(27%-22.45%)*2×25%+(21%-22.45%)*2×20%+(32%-22.45%)*2×15%)*1/2
        =(0.0355*2×10%+(-0.1145)*2×10%+(-0.0745)*2×20%+0.0455*2×25%+(21%-22.45%)*2×20%+(32%-22.45%)*2×15%)*1/2
        =(0.0355*2×10%+(-0.1145)*2×10%+(-0.0745)*2×20%+0.0455*2×25%+(-0.0145)*2×20%+(32%-22.45%)*2×15%)*1/2
        =(0.0355*2×10%+(-0.1145)*2×10%+(-0.0745)*2×20%+0.0455*2×25%+(-0.0145)*2×20%+0.0955*2×15%)*1/2
        =0*1/2
        =0/2
        =0
    答案:((26%-22.45%)*2×10%+(11%-22.45%)*2×10%+(15%-22.45%)*2×20%+(27%-22.45%)*2×25%+(21%-22.45%)*2×20%+(32%-22.45%)*2×15%)*1/2=0
