Question 29

If all the vowels of the word COMPUTER are taken together, the letters of the word COMPUTER can be arranged in how many different ways ?

If all the three vowels are taken together, they can be considered one element and so, the number of elements = 6

Number of ways of arranging the 6 elements = 6!

The vowels can be re arranged in the element in 3! ways.

So, total number of ways of arranging = 3! x 6! = 4320 ways
