How many different ways can the letters of the word corporation be arranged so that the vowels always come together?

Nội dung chính

  • The correct option is A 50400In the word 'CORPORATION', we’ll treat the vowels OOAIO as a single letter. Thus, we have CRPRTN (OOAIO). This has 7 (6 + 1) letters of which R occurs 2 times and the rest are different. Number of ways of arranging these letters =7!2!!=2520 Now, 5 vowels in which O occurs 3 times and the rest are different, can be arranged In 5!3!=20 ways Therefore, Required number of ways =(2520×20)=50400

Solution

The correct option is A 50400In the word 'CORPORATION', we’ll treat the vowels OOAIO as a single letter. Thus, we have CRPRTN (OOAIO). This has 7 (6 + 1) letters of which R occurs 2 times and the rest are different. Number of ways of arranging these letters =7!2!!=2520 Now, 5 vowels in which O occurs 3 times and the rest are different, can be arranged In 5!3!=20 ways Therefore, Required number of ways =(2520×20)=50400

Question Detail

  • 5760
  • 50400
  • 2880
  • None of above

Answer: Option B

Explanation:

Vowels in the word "CORPORATION" are O,O,A,I,O
Lets make it as CRPRTN(OOAIO)

This has 7 lettes, where R is twice so value = 7!/2!
= 2520

Vowel O is 3 times, so vowels can be arranged = 5!/3!

= 20

Total number of words = 2520 * 20 = 50400

1. A box contains 4 red, 3 white and 2 blue balls. Three balls are drawn at random. Find out the number of ways of selecting the balls of different colours

  • 12
  • 24
  • 48
  • 168

Answer: Option B

Explanation:

This question seems to be a bit typical, isn't, but it is simplest.
1 red ball can be selected in 4C1 ways
1 white ball can be selected in 3C1 ways
1 blue ball can be selected in 2C1 ways

Total number of ways
= 4C1 x 3C1 x 2C1
= 4 x 3 x 2
= 24

Please note that we have multiplied the combination results, we use to add when their is OR condition, and we use to multiply when there is AND condition, In this question it is AND as
1 red AND 1 White AND 1 Blue, so we multiplied.

2. Evaluate permutation equation \begin{aligned} ^{59}{P}_3 \end{aligned}

  • 195052
  • 195053
  • 195054
  • 185054

Answer: Option C

Explanation:

\begin{aligned}
^n{P}_r = \frac{n!}{(n-r)!} \\
^{59}{P}_3 = \frac{59!}{(56)!} \\
= \frac{59 * 58 * 57 * 56!}{(56)!} \\
= 195054
\end{aligned}

3. In how many words can be formed by using all letters of the word BHOPAL

  • 420
  • 520
  • 620
  • 720

Answer: Option D

Explanation:

Required number
\begin{aligned}
= 6! \\
= 6*5*4*3*2*1 \\
= 720
\end{aligned}

4. Evaluate permutation equation \begin{aligned} ^{75}{P}_2\end{aligned}

  • 5200
  • 5300
  • 5450
  • 5550

Answer: Option D

Explanation:

\begin{aligned}
^n{P}_r = \frac{n!}{(n-r)!} \\
^{75}{P}_2 = \frac{75!}{(75-2)!} \\
= \frac{75*74*73!}{(73)!} \\
= 5550

\end{aligned}

5. How many words can be formed by using all letters of TIHAR

  • 100
  • 120
  • 140
  • 160

Answer: Option B

Explanation:

First thing to understand in this question is that it is a permutation question.
Total number of words = 5
Required number =
\begin{aligned}
^5{P}_5 = 5! \\
= 5*4*3*2*1 = 120
\end{aligned}

    what has 7 letters?
    I only counted 6 consonants and 5 vowels.

    mastguru 8 years ago replied

    Hello Fernando,

    As per solution we have written like CRPRTN(OOAIO)

    Here we take it 7 letters , 6 (CRPRTN) + 1 (OOAIO), as we need to vowel always come together, this way we counted them 7. Then solved the question.
    Hope it helped you..
