ICICI BANK FPO Priced at 940 Rs and for retailers at 890 Rs

ICICI Bank FPO price has been fixed at 940 rs per share and also they have fixe the ADS at American depositary share at $49.25 per share so this will be also some where in the range of 1000 rs or so .As we all know that retailers doesn't need to pay the same price as other FII and QIB's , there price would be at 890 Rs per share which is like good profit considering the price of 950 rs in the secondary market , but one thing i don't understand is not sure how much profit it would have got them , like investment of hundred shares is like 90000 Rs which would yield them 96000 rs which is mere profit of 7 percentage
