bhai can you tell answer of this also , How many different words can be formed using all the letters of the word ALLAHABAD

0

ok almost all of us solve this by using 9! / 4! 2! = 7560

but bro they are asking different words so we have to subtract -1 becuase allahabad is also there in 7560 , so 7560-1 = 7559 what do u think ?

@sumit goyal 1 see, this is the question of permutation and combination where they will ask what are the different permutation of the given word and You have to find all those permutations possible, and the word given in the question is also a permutation of the given word, and whatever answer you calculate contain that permutation also.

So, they will ask you different permutations which in your case you have calculated.

Secondly,

they are asking different words so we have to subtract -1 becuase allahabad is also there in 7560 , so 7560-1 = 7559 what do u think ?

No, you do not have to subtract 1 from your answer.

If they will say like this:-

What are the different numbers of permutation of the word ALLAHABAD

other then given permutation.

then, in this case, you have to subtract 1, because in 7560 permutations it is also calculated, So, to obtain differently we have to subtract 1.

But not in this case.

No, you don't need to subtract 1 from the result, ALLAHABAD is also a different word, which is not present in remaining 7559 results.
