(A) 1324
(B) 1500
(C) 1800
(D) 1890
Correct Option is: C
The word ‘WAGGISH’ contains 7 letters of which 1 letter occurs twice
= 7! / 2!
= 2520
No. of permutations possible with vowels always together = 6! * 2! / 2!
= 1440 / 2
= 720
No. of permutations possible with vowels never together = 2520-720
= 1800.
