    Re: a a tricky one

    I think you can make 25 soaps and you will stil have 1 part with you

    Wrote a simple algo to find that in perl



    $w = 251;
    print w2soap(\$w);
    sub w2soap {
    my($wref)=@_;
    my $x = int($$wref/11);
    $$wref = $x + ($$wref % 11);
    if($$wref >= 11){
    $x = $x + w2soap($wref);
    }
    print "Returning $x\n";
    return $x;
    }

    Re: a a tricky one

    Hi,

    I think it's 25.

    Because form 251 scraps you can make 22 soaps and 9 scraps remain. And by making 22 soaps you will get 22 more scraps so from that you can make 2 more soaps. And by making those 2 soaps you will get 2 scraps. And those 2 scraps with the previously remained 9 scraps will make one more soap. And for the last one you made, you'll get one more scrap. That of course will be the reminder.

    No. of soaps are 22+2+1 = 25

    So, there will be 25 soaps and 1 scrap.

    Re: a a tricky one

    Answer: 25 soups

    11 scraps = 1 soup manufactured ( given )

    With 251 scraps = 22 soups manufactured, and each soup gave one scrap i.e. 22 scrap + 9 scrap still remained. So, now we total 22+9 = 31 scraps still remained.

    With 31 scraps = 2 soups manufactured, and each soup gave one scrap i.e. 2 scraps + 9 scrap still remained. So, now we have 2+9 = 11 scraps still remained.

    With 11 parts = 1 soups manufactured, and it gave one scrap.

    In Total, 22 + 2 + 1 i.e 25 soups . ( with 1 scrap still remained.)

    But the question was how many soaps can be manufactured?? so the answer to it is ' 25 ' soups can be manufactured by end of the day. !!..
    Forget about the scraps they aren't asking about remained scraps.

    Few have answered it correctly ... 3 cheers.

    Cheers,

    Re: a a tricky one

    Answer for ramprasad.ap question.

    Question:
    Now a similar question
    If for every 3 wrappers I get 1 soap free ( with wrapper of course )
    How many soaps do I need to buy to get 20 soaps

    Answer:
    To buy get 20 soups you need to buy atleast 14 soups.

    Explanation:
    Buy 14 soups, you will have 14 soups + 14 wrappers,

    With 14 wrappers, you can have 4 soups and along with it 4 wrappers + 2 wrappers remaining. Total you have 6 wrappers left.

    With 6 wrappers, you can have 2 soups and 2 wrappers. So in total you have (14 +4 +2 soups + 2 wrappers still remaining ).

    Ramprasad is this OK ? Kindly confirm.


    Cheers,
    Anup | Mahindrakar

    Ans: 25 (22+2+1)

    (251 %11) +(22%11) +1)

    Re: a a tricky one

    It should be 21 soap i.e,
    Step 1: 251/11 =22.81 approximately 23 soaps(23*11=253)
    Step 2:Remove a part as a scrap from 23 soap(253-23=230)
    Step 3:Now divede 230 by 11 its approximately 21(20.90)
