    1) calculate all possible combinations of words tha can be made with A fixed 2)do the same with C, H, I, N 3) now we have S and luckily the 1st wrd that can be made starting with S is SACHIN :P so can u do it now :)

    there are 120 "words" per starting letter the first 5 groups use up 600 slots SACHIN will be in slot 601
