- here in the word LEADING,vowels are E,A,I.we want to arranged tat word such that vowels always comes together i.e in the form LDNG(EAI).So now word treated as a 5 alphabet word cause (EAI) treated as a single alphabet.
5 alphabets in the word can be arranged in =!5=120 ways
3 alphabets in(EAI) can be arranged in=!3=6 ways
total no of ways of arrangement so that voweles always come together=120*6=720.

- in the word LEADING, E,A,I are the vowels that we want vowels come to gather i.e.
3 vowels can grouped in
5 alphabets can be arranged in =5!=120 ways
3 alphabets can be arranged in=3!=6 ways
total no of ways vowels always come to gather=120*6=720 ways
ans is : (c) - 10 years agoHelpfull: Yes(2) No(3)
- in the word LEADING vowels are E,A,I and these are always come together so that the arrangement is
LDNG(EAI) hence 5!
vowels E,A,I has 3!
answer=5!*3!=720 - 6 years agoHelpfull: Yes(0) No(0)
- 5! * 3! =720.
