In how many ways the word CATHOLICS are arranged such that all that all the vowels should be in odd positions.
Read Solution (Total 14)
-
- (5p3)*(6!/2!)
- 5 years agoHelpfull: Yes(17) No(1)
- the answer is 43200.
explanation:- First we have to take nine places because the given word as nine characters and we have to find vowels we have three vowels and five odd places i.e; 5P3*6! = 43200 - 6 years agoHelpfull: Yes(8) No(6)
- according to me,
no.of consonants are 6(C,T,H,C,L,S)
no.of vowels are 3(A,O,I)
first of all arrange all consonants,no.of ways of arranging consanants are 6!/2!(because 2 C's are repeated)
now arranging 3 vowels in 6 odd places is 6C3*3!
finally,no.of ways are 6!/2!*6C3*3! - 6 years agoHelpfull: Yes(4) No(3)
- total no. of vowels=3
total no. of consonants = 6
and total odd position =5(1,3,5,7,9)
so,vowels are arranged in =5C3*3! ways
so,result is
5C3*6!*3!=43200 - 6 years agoHelpfull: Yes(3) No(3)
- no.of consonants are 6(C,T,H,C,L,S)
no.of vowels are 3(A, O, I)
no.of odd places are 5
first of all, arrange all consonants,no.of ways of arranging consonants are 6!/2! (because 2 C's are repeated)
now arranging 3 vowels in 5 odd places is 5C3*3!
finally,no.of ways are 6!/2!*5C3*3!=21600 - 4 years agoHelpfull: Yes(3) No(0)
- Answer:
21600
Step-by-step explanation:
CATHOLICS
Vowels - A O I
Consonant - C , T , H , L S C
Odd positions 1 , 3 , 5 , 7 , 9 = 5 Posistions
all the vowels
3 Vowels can be positioned
in ⁵P₃ = 5!/(5-3)! = 5!/2! = 60
Remaining positions
9 - 3 = 6
6 Positions can be filled
in 6!/ 2! ways as C is repeated
= 360
Total = 360 * 60
= 21600 - 3 years agoHelpfull: Yes(1) No(0)
- 3 vowels can be arranged in 5 odd places i.e; 5C3=10
6 consonants can be arranged in 4C6 ways i.e; 6
Total is 6*10=60 - 6 years agoHelpfull: Yes(0) No(1)
- there are 3 vowels.so the number of ways they can be arranged in 5C3.
the remaining can be arranged in 6! ways.
therefore, total ways are 6!*5C3 - 6 years agoHelpfull: Yes(0) No(0)
- Total number of places are:9
odd places are :5
Vowels are: a,o, i =3.
So we can place 3 vowels in any 5 places=5p3=20
After you placed 3 vowels they are 6 places are empty yet and we need to place all 6 consonants.
So 6p6=720.
Total=20*720=14800 - 6 years agoHelpfull: Yes(0) No(1)
- The answer is 43200.
We had put all the vowels in one box and to arrange all this three vowels no of ways is 3! .
There are 9 places were present and to arrange all the letters no of ways is 6! Because we have remove 3 three. So the total letter will be 6.
Finally:-6! ×3! =43200 - 5 years agoHelpfull: Yes(0) No(0)
- 5c3*5!=7200
- 5 years agoHelpfull: Yes(0) No(1)
- the answer is 7200
- 5 years agoHelpfull: Yes(0) No(0)
- 3 vowels can be placed in 5 places in 5p3 ways and 6 consonents in 6 places in 6! Ways
Ans:5p3×6!
=60*120
= 43200 - 4 years agoHelpfull: Yes(0) No(2)
- 5p3*(6!/2!)
- 1 Month agoHelpfull: Yes(0) No(0)
