A) 360
B) 114
C) 72
D) 54
Correct Answer: C
Solution :
First, we arrange 3 consonants in \[3\ !\] ways and then at four places (two places between them and two places on two sides) 3 vowels can be placed in \[^{4}{{P}_{3}}\times \frac{1}{2\ !}\] ways. Hence the required number\[=3\ !\ {{\times }^{4}}{{P}_{3}}\times \frac{1}{2\ !}=72\].You need to login to perform this action.
