1. 120 ways
2. 230 ways
3. 320 ways
4. 210 ways
5. 250 ways

## Answer (Detailed Solution Below)

Option 1 : 120 ways

Given:

A word "PARROT" with has 5 letters from which 4 consonants and 2 vowels.

Formula used:

Factorial n! = n × (n - 1) × ..... × 3 × 2 × 1

Calculation:

The arrangement is made in such a way that the vowels always come together.

⇒ "PRRT(AO)"

Considering vowels as one letter, 5 different letters can be arranged in 5! ways.

We have two "R" also = 5!/2!

⇒ 5!/2! = 60 ways

The vowels "AO" can be arranged themselves in 2! ways.

⇒ 2! = ways

Required number of ways = 60 × 2 = 120 ways.

∴ "PARROT" can be arranged in such a way that the vowels always come together for that we have 120 ways.

In how many different ways can the letters of the word 'MATHEMATICS' be arranged so that the vowels always come together?

 A. 10080 B. 4989600 C. 120960 D. None of these

Explanation:

In the word 'MATHEMATICS', we treat the vowels AEAI as one letter.

Thus, we have MTHMTCS (AEAI).

Now, we have to arrange 8 letters, out of which M occurs twice, T occurs twice and the rest are different. Number of ways of arranging these letters = 8! = 10080. (2!)(2!)

Now, AEAI has 4 letters in which A occurs 2 times and the rest are different.

 Number of ways of arranging these letters = 4! = 12. 2! Required number of words = (10080 x 12) = 120960. ## Why Aptitude Permutation and Combination?
