how many arrangements will start and end with a vowel for TOGETHER?
Read Solution (Total 7)
-
- The vowels can be arranged at start and end as O..E E..O E..E so 3 ways
Consider the vowels as a single unit. You'll have
TGTHR(OEE) (6!/2!)*3 = 1080 - 11 years agoHelpfull: Yes(24) No(6)
- Case 1 : when first letter is "o"
the arrangements of other letters will be 6!/2!
case 2 : when first letter is "e"
the last letter will be either "o" or "e"
so the arrangements of other letters will be (2 x 6!/2!)
So the total arrangements for start and end with a vowel for TOGETHER will be
(3 x 6!/2!) = 1080 - 11 years agoHelpfull: Yes(13) No(6)
- No of ways to arrange vowels at first and last position is 3!/2!=3.
No of wasy of arranging remaining 6 letters=6!.
So total no of ways=3*6!. - 11 years agoHelpfull: Yes(3) No(3)
- total 8 letters...consider vowels as one group so 6 can be arranged in 6!ways and T is repeated=6!/2! nd vowels can be arranged in 3p2/2!(3p2=3!/1!=3)...so tatal (6!/2!)*3

- 3C1 for selecting vowels n 6!/2!*2! = 1080
- 11 years agoHelpfull: Yes(1) No(1)
- @Tejvansh: SO yu mean "e" can be repeated,but not "t"??
- 11 years agoHelpfull: Yes(0) No(1)
- for vowels at 1st nd last position 3!/2!
and now we are left with 6 places and 6 letters which can now be arranged as 6!
So i think answer will be 3*3*6! - 11 years agoHelpfull: Yes(0) No(2)
