Hint: In this question, we first need to find the total number of arrangements possible with the given letters of the word using the permutation formula given by \[{}^{n}{{P}_{r}}\]. Then we need to find the number of words in which two vowels are together but first selecting the two vowels and then arranging all the letters using the formula \[{}^{n}{{C}_{r}}\]. Now, find the number of words in which 3 vowels are together and then subtract 2 vowels together from total words and add 3

Solution The correct option is C14400The explanation for the correct answer.Find the number of ways such that no two vowels occur together.Given: TRIANGLEThe total number of letters in the word triangle is 8.The total number of words that can be formed =8!=40320.The total number of words in which two vowels occur together =C2×7!×2!= 302403.The number of ways where all vowels occur together =C3×6!×3!= 43203.Therefore required number of words =40320-30240+4320=14400.Hence option (C) is the correct answer.
