# QA – Placement Quizzes | Permutation and Combination | Question 2

What is the number of possible words that can be made using the word “QUIZ” such that the vowels never come together?**(B)** 8**(C)** 12**(D)** 16**(E)** 24**Answer:** **(C)****Explanation:** The word “QUIZ” has 4 letters in which “UI” are vowels.

Total number of possible words = 4!

Treating “UI” as a single letter we can make words in 3! ways.

“UI” can be arranged in 2! ways.

Therefore, the number of words can be made using vowels together = 3! * 2! = 12 ways.

Hence, the number of words can be made such that vowels never come together = 24 – 12 = 12 ways.
