How many words can be formed by re-arranging the letters of the word ASCENT such that A and T occupy the first and last position respectively?
Read Solution (Total 9)
-
- A and T should occupy the first and last position, the first and last position can be filled in only one way. The remaining 4 positions can be filled in 4! Ways by the remaining words (S,C,E,N). hence by rearranging the letters of the word ASCENT we can form 1x4! = 4! words

- A and T are in the first and last position besides that we have 4 letters so 4!=24 number of words we can form..............,

- if the letters can be repeated then it can form 4 words excluding ascent.

- letters A and T have to occupy constants positions, so we should not considering them, then the letters S,C,E,N have to be arranged in the form of factorial i.e. 4!= 36
So the final answer is 36 - 13 years agoHelpfull: Yes(0) No(34)
