- 9 years agoHelpfull: Yes(1) No(0)
- _ _ _ _ _ _
Here we have 6 letter word where 'E' appears twice
therefore No.of ways = 6 !/2!
720/2 = 360 Ans. - 9 years agoHelpfull: Yes(1) No(0)
- right answer is 6!/2! = 360. last one is not right
- 9 years agoHelpfull: Yes(1) No(0)
- 6! / 2! = 360
- 9 years agoHelpfull: Yes(1) No(0)
- 720
6*5*4*3*2*1 - 9 years agoHelpfull: Yes(1) No(2)
- 6!/2=720/2=360
- 9 years agoHelpfull: Yes(1) No(0)
- it's very simple
total letters=6
e is repeated two times
hence correct ans is :6!/2!=360 - 9 years agoHelpfull: Yes(1) No(0)
- ANSWER IS 1)None of these.
while doing arrangement we does not count the word itself
so, 6!/2!-1=359.the correct one which is not in options. - 9 years agoHelpfull: Yes(1) No(1)

so 6 word of letter and E is the repeat word
becouse 6-2=4letter and 2 word are counting one word that is total word is 5!/2!=60 - 9 years agoHelpfull: Yes(0) No(4)
- 6!/2!=360
total no of word!/total repetead word! - 9 years agoHelpfull: Yes(0) No(0)
- ans is 360
- 9 years agoHelpfull: Yes(0) No(0)
- ans----(3) 360
no of ways of arrangement = 6! / 2! =360
- 9 years agoHelpfull: Yes(0) No(0)
- LEADER=6!/2!=6*5*4*3*2*1/2=360
- 9 years agoHelpfull: Yes(0) No(0)
- 6!/2! =6*5*4*3*2*1/2 =360
Option 3) 360 - 9 years agoHelpfull: Yes(0) No(0)
