A. HKD1 = CNY ( 6.8270/7.8000 - 6.8280/7.8000 )
B. HKD1 = CNY ( 6.8270/7.8010 - 6.8280/7.8010 )
C. HKD1 = CNY ( 6.8270/7.8000 - 6.8280/7.8010 )
D. HKD1 = CNY ( 6.8270/7.8010 - 6.8280/7.8000 )
A. HKD1 = CNY ( 6.8270/7.8000 - 6.8280/7.8000 )
B. HKD1 = CNY ( 6.8270/7.8010 - 6.8280/7.8010 )
C. HKD1 = CNY ( 6.8270/7.8000 - 6.8280/7.8010 )
D. HKD1 = CNY ( 6.8270/7.8010 - 6.8280/7.8000 )
