@ganeshie8 plss needed ur hlp
That looks good! \[4*5*5*1\]
but answer in the text book is 76
first i used the same thing u used
but answer is 76
there is overcounting somewhere
here all number would be divisble by 2 also
are u stuck @ganeshie8
is also did the same thing as u did but i closed the question the again wrote but answer is 80
should i give the options
The 1 st part was the number of such numbers which are even using S
but amswer is given as 404
@ganeshie8 are u there
Can it be done using permutations?
yes it is a permutation and combination ques
Why have you omitted zero? It should be included. Isn't it @ganeshie8 ?
\(4*5*5*1\) is the correct answer for the main question your textbook is wrong
i was thinking so are u sure
also \(4*5*5*5\) is the correct answer for your later question your textbook is wrong again, just make sure you're looking at the correct chapter for answers
but i dont think so
Got it. First number shouldn't include zero. I am dumb. :D
is there a reason you don't think so other than the textbook answer
cause there are three parts of the question and the first part is right
whats the first part
repetiton not allowed
did you get 24 for that ?
repetition not allowed
@ganeshie8 can u ask for help from somebody who is good at premutation because i think the textbook is right
