do they define what a "word" is ?

example ACIHSN is a word
well the question makes sense only if we can make any random wrd
we can also conclude that repetition is not allowed :)
there are 6! of the words there as repetion is allowed
and S starts from 5 last 5! =120
yes, but we will get 601 using that.
but 6!-5!=600 but the answer is 601 , i m confused on that
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
but that is no where near your answer choices of about 160
yea 601 is the answer :)
oh lol yea
i wrote the choices incorrectly it was supposed to be 599,600,601,602
hehe e.e XD
playing a joke on me! how mean!
