  1. Who am I?

    From the OP it is clear that statements [7 & 8] are both either true or lie.


    CASE - 1
    Assuming both as true, we get the following results:
    Statement [1] is lie, as seven of them couldn't be lying.
    [2] is lie, as six of them couldn't be lying if [2] was true.
    [3] & [4] are both either lie are both true. So [3] & [4] both are lies, as five of them couldn't be lying if [3] & [4] both were true.
    Either one of [5] & [6] could be true, so [5] couldn't be true, if [6] was a lie. Also [6] couldn't be true if [5] was a lie. Therefore both are lie.
    Conclusion of above: If [7] & [8] were true, thenl other six would be lying, which would make the statement [2] - true, So case - 1 is not possible.
    CASE - 2:
    [7] & [8] both are lying. then all of the statements become lie except [1]. Therefore Case - 2 is correct. Both [7] & [8] are lying hence [7] is Bill and [8] is Susan.

  4. the only one

    O has no edges, while all other alphabets have edge, therefore O is the only one alphabet which is unique.

    you mean straight edge? look closer on the sides..also they all look 2D thus all are edged

    I also think 'edge' word does not suit here. But what would we call it if there is no end .... I mean O is the letter which ends there - where it starts.

  5. Magic Square!

    Make two circle with equal diameter. Cut both of them into half, so that four halves are available. Now.two halves may be put together in such a way that the curved surfaces touche each other and diameter sides are parallel to each other - say you get a fig. 'A'. Now put two halves of other circle over fig. 'A' in such a way that diameter sides are at 90 degree to the dimeter sides of fig. 'A' and the curved surfaces touch each other at the same point where those of first circle are in touch. You will get a Square with a flower design inside.

  7. Guess the Numbers

    in New Logic/Math Puzzles

    Posted

    Since A & B are given the consecutive numbers therefore the numbers must be 2 & 3, considering that zero has no value so not counted as number, and no negative or fractional quantity is chosen.


    Explanation is: when first time asked 'A' could not answer because he had two and 'B' could have any of the number 1 or 3; Then when B is asked he could not reply because he had number 3, and A could have any number 2 or 4. But B's answer ascertained A that B did not have 1, otherwise he could have definitely known that A has numbere 2 (zero is not considered as number). Therefore obviously A comes to know that B has Number 3.

  14. Convent Garden Problem

    in New Logic/Math Puzzles

    Posted

    Say they had x no. of apples each.


    Cost of Mrs. Smith’s apples = x/3 penny
    Cost of Mrs. Jones’ apples = x/2 penny
    Real cost of total apples = x/3 + x/2 = 5x/6 penny
    Cost of 2x no. of apples sold by Mrs. Jones = 4x/5 penny
    The difference was 7 penny short.
    So 5x/6 – 4x/5 = 7
    Solving this we get x = 210 No.
    Mrs. Smith should have got = 210/3 = 70 penny.
    Mrs. Jones should have got = 210/2 = 105 penny
    Mrs. Smith sold total 420 No. apples for = 4*210/5 = 168 penny
    They divided it equally each taking one-half, so each got = 168/2 = 84 penny.
    Mrs. Jones lost 105 – 84 = 21 penny.

  23. Win or Lose.......?

    In a Men's hockey world cup, seven countries participated. In the league, each country earned points as under:

    India - 10 points

    Argentina - 10 points

    Holland - 8 points

    Australia - 6 points

    Malaysia - 3 points

    Russia - 3 points

    Kenya - 2 points

    Note: The point system was as under:

    For each match won: 2 points

    For each match tied: 1 points

    For each match lost: 0 points

    Following facts are known:

    [A] Number of matches won by Holland, are equal to half the number of matches tied by it.

    Kenya defeated Russia in a match, in which Russia coud score 2 goals against 3 goals by Kenya.

    [C] Australia had not a single match tied against any country.

    With the help of above information, can you find the results of all the league matches in this tournament?

    Note: There is no typo error this time. However if any clarification needed please ask...!

  24. Who teaches so loudly??

    in New Logic/Math Puzzles

    Posted · Edited by bhramarraj

    Because the translation program s/he used is silly? ( The "last name as Sharma" part seems really weird to me when I say it out loud. I wasn't a fan of English class, is this a correctly formed sentence? )

    A typo?

    Because s/he is performing an experiment based upon our reaction to said "clue".

    The electronic internet kittehs that live in the net got the words mixed up when delivering the post to the database.

    I favor #4 personally.

    btw, I did find this puzzle somewhat amusing when I made the standard box thing and filled it in. ( The one most logic puzzle use. Does it have a name? )

    -edit-

    And I just realized that internet kittehs that live in the net is redundant but in a fun way.

    Really a typo error there in the sentence, The sentence should be "One of the teacher's last name is Sharma." Thank you all for pointing it out. But the puzzle I found interesting. It was actually published in a Magazine, and the names used were strange to me. So I replaced the names. However I appologise for the inconvenience caused to some of the friends.

  25. Who teaches so loudly??

    in New Logic/Math Puzzles

    I put this one down to the miscommunication of a non-official clue based on certain non-English languages having non-gender specific personal identifiers.

    I am sorry, but if anybody has any doubt about any portion of the puzzle, e.g. about names gender etc, clarification might be asked for. However there was no need of separate clarification about the genders though. What so ever, there are correct solutions are also recieved. And I am also posting the correct solution here, with logical explanation.

    From clue [1]: Tripathi teaches either in A2 or A3, so as to have two neighbors who get disturbed by her loud voice.

    From clue [2]: There are four teachers, one is Lalita, second is a teacher who teaches in A2, third is Verma who does not teach in A3, and fourth teacher is Prashant – the only male teacher.

    Here clue [2] becomes very informative as it reveals following additional facts also:

    (a) Lalita does not teach in A2.

    (b) Last name of Lalita is not Verma.

    © Last name of Prashant is not Verma.

    (d) Verma does not teach in A2 (as well in A3, as already mentioned in OP).

    (e) Prashant does not teach in A2, (it is obvious because as per narration in OP also, Tripathi is a lady teacher).

    From clue [3]: Sushma does not teach at either end of classrooms block, therefore she teaches either in A2 or A3.

    ASSUMPTION 1:

    Let us assume Tripathi teaches in A2, then Sushma and Mishra would teach in adjacent rooms A1 & A3. Then from clue [3], Sushma would teach in A3, and hence Mishra would teach in A1.

    From clue [2] first name of teacher in A2 should not be Lalita; Sushma and Prashant do not teach in A2, and then only first name remains for teacher in A2 is Sushila.

    From clue [2], last name of Sushma (being the class teacher in A3) could not be Verma, and Mishra and Tripathi are the last names of teachers in A1 and A2 respectively. So only last name remains for Sushma is Sharma.

    Now only class room remained for Verma is A4. Also as per clue [2]©, Prashant could not have Verma as his last name. So only last name remained for Prashant is Mishra. Then only Lalita could have her last name as verma which is contradictory to the conclusion 9b0 of clue [2].

    Therefore Tripathi does not teach in classroom A2 but teaches in classroom A3.

    Sushma and Mishra teach in adjacent classrooms A2 & A4. Sushma does not teach at the end of the block, so she teaches in A2, and Mishra teaches in A4.

    As per clue [2](d), Sushma is not Verma, Mishra teaches in A4, Tripathi teaches in A3, then only last name remains for her is ‘Sharma’.

    Hence SUSHMA SHARMA teaches in A2.

    From clue [2]©, Prashant is not Verma. Tripathi is a lady, so Prashant is not Tripathi. So prashant has only one option left – his last name is Mishra.

    Hence PRASHANT MISHRA teaches in A4.

    Lalita is not Verma as per clue [2](b), therefore Sushila is Verma, and remaining Lalita is Tripathi.

    Hence LALITA TRIPATHI teaches in A3.

    And SUSHILA VERMA teaches in A1.
