MCQ
The number of words, which can be formed using all the letters of the word "DAUGHTER", so that all the vowels never come together, is
  • A
    34000
  • B
    37000
  • 36000
  • D
    35000

Answer

Correct option: C.
36000
(C)
DAUGHTER
Total words $=8$ !
Total words in which vowels are together $=6!\times 3!$ words in which all vowels are not together$
\begin{array}{l}
=8!-6!\times 3! \\
=6![56-6] \\
=720 \times 50 \\
=36000
\end{array}
