in how many ways can the letters of the word, ‘language’ be arranged in such a way that the vowels always come together?
The number of ways is 720.
Step 1: Understand the word “LANGUAGE”
Write the letters and count each:
- L – 1
- A – 2
- N – 1
- G – 1
- U – 1
- E – 1
So:
- Total letters = 8
- Vowels = A, A, U, E → 4 vowels (with A repeated twice)
- Consonants = L, N, G → 3 consonants
We need arrangements where all vowels stay together.
Step 2: Treat all vowels as one block
Imagine the 4 vowels “A A U E” as one super-letter (a block). Now the objects to arrange are:
- [VOWEL-BLOCK]
- L
- N
- G
So we have 4 objects in total. Number of ways to arrange these 4 distinct objects:
4!=244!=244!=24
Step 3: Arrange the vowels inside their block
Inside the vowel-block we have: A, A, U, E If all four were different, there
would be 4!=244!=244!=24 arrangements,
but there are two identical A’s , so we divide by 2!2!2!:
Arrangements of vowels=4!2!=242=12\text{Arrangements of vowels}=\frac{4!}{2!}=\frac{24}{2}=12Arrangements of vowels=2!4!=224=12
Step 4: Combine both parts
Total valid arrangements =
(arrangements of the 4 objects) × (arrangements of vowels within block)
=4!×4!2!=24×12=288=4!\times \frac{4!}{2!}=24\times 12=288=4!×2!4!=24×12=288
Wait – that suggests 288, but we must double-check the consonant count carefully. Recheck letters: L, A, N, G, U, A, G, E Notice: G appears twice , not once. Correct counts:
- L – 1
- A – 2
- N – 1
- G – 2
- U – 1
- E – 1
So:
- Vowels: A, A, U, E → 4 letters (A repeated twice)
- Consonants: L, N, G, G → 4 letters (G repeated twice)
- Total letters = 8 (still fine)
Now, treat all vowels as one block: Objects to arrange:
- [VOWEL-BLOCK]
- L
- N
- G
- G
That is 5 objects , with G repeated twice. Number of ways to arrange these 5 objects:
5!2!=1202=60\frac{5!}{2!}=\frac{120}{2}=602!5!=2120=60
Arrangements of vowels inside the block are still:
4!2!=12\frac{4!}{2!}=122!4!=12
So the correct total :
Total ways=60×12=720\text{Total ways}=60\times 12=720Total ways=60×12=720
Final Answer
