I think there are 2 options which satisfy the given conditions in the question posted on 28.12.09.

If only integer prices are alloed , then one option.

In today's qn, I think

In place of 1000 kilowatt per hour consumption of electricity is known as 1 unit ,

It should be

1000 watt per hour consumption of electricity is known as 1 unit

Check out the placement puzzles page... There are so many puzzles to be solved. These should be put up at the main puzzle page. Also, please check the puzzles page, some of the questions do have received right answers in the comments and are still set with status "Unsolved".

It feels pity that so many people got right answer to 09-Dec-2009 puzzle and yet, no one had a comment to match with the admin's logic. Also, I agree with Mr. Daniel. The puzzles posted must be of solving type in Mathematics and logic, and not find odd one out and other find code type. It feels very boring when the volume of such coding puzzles increase. Once in a fortnight, it is ok to have some codes or so. But other days, there must be well-solvable logically challenging maths problems.

for the puzzle yesterday i.e. 7/12/2009 answer shown by ADMIN is FOOT i.e. option 3.... However, you awarded points to some other people who gave answer as FUN i.e. Option 10.

How can you award points like that...? As there can be only one answer. that is what ever admin gives that will be final...

Please clarify this....

I agree with Daniel.

I think I have also answered option 10 ( FUN) as my answer but got -1 marks.

That last puzzle wasn't exactly reasonable... sure, "FOOT" was the only word with a double letter, but you could just as well say that "FIGURE" was the only one with three vowels (or with six letters), and "FUN" was the only one where the letters added up to a prime (which seems *much* more reasonable than the other option.) You could easily come up with just-as-reasonable justifications for several other options as well.

I certainly don't think I should *lose* points for not guessing the particular criteria you wanted when there were several other that were no more or less reasonable.

Again, if there were more problems that actually stated a math problem and fewer that asked you to find a pattern in a series of words, this wouldn't be such a huge issue.

If we could get a few more puzzles that are actually well-posed math problems and a few less that consist of "ABCDE = 15, PQRST = 12, keep guessing patterns until one works out!" I feel it would be a good thing.

21-nov-09 puzzle: yeah. it is right. there are two sets. the correct answer should have been 90. but look at this: it is given that amit got a first class certificate. how will anyone get a certificate for scoring 9 out of 100? may be the m4maths team considered only those scores which amit had to score for a win in all subjects.

problem with Saturday's (21-nov-09) puzzle

In that puzzle, sum of marks should be 339.

possible numbers are 81,81,64,64,49
and
100,100, 81,49,9

so total possible arrangements were 30+60=90.

but 90 was not in options.

The new looks of the site is amazing. Dear admin, will you please clear my doubts? It has been displayed that be one among top 5 to win prizes. By that, did you mean that top 5 people of a week will get the respective prizes every week? Or is the minimum cut-off of 80 points still valid? I would also like to point out that m4maths is printed out wrongly as 'm4amths' in the today's puzzle page, just above today's puzzle, where the italic writing has been employed. Once again, the new looks are awesome.

Dear Admin

todays question was "Three non parallel tangents are drawn in a circle. What is the probability that it would be an incircle."

As I understand the meaning, "We are given with a circle and then we are trying to draw 3 tangents which are not parallel to each other. Now we have to calculate whether the given circle will be an incircle or not."

For a case of 3 non parallel tangents, it will always be a circle.

The answer could have been 1/4 if the question was given something like "a circle is given and three [b]Random[/b] tangents are drawn.. whats the probability that it is an incircle?"

Kindly check my logic

Nice suggestions.
I would like to suggest admin to check the logic given by other members also to check if there is any controversial option .In such questions , there may be more than one possible solutions depending on approach of individual. The time limit can be given up to 11 PM and result can be declared at 0000 hrs or later after checking the solutions/logics given by members.

Dear admin, since I have started to like the concept of the website, I would like to point out a few things that do not look so good.

The introduction says: "Warning: Please think before Joining (girls)."

What is the purpose of mentioning (girls) in this statement? Is it any subtle kind of pun that I don't understand or even find tasteful?

And secondly, why is the linguistic level so bad on this website? There are too many errors throughout the webpages. It would certainly help to correct them.

Dear admin, thank you for considering my suggestion. I would like to make into your notice a mistake. In the "maths quotes" page, one quote has been cited twice, each time, it appears to be said by different people. Can you clarify that? It is just, Math is always perfect and I would like our site to be too. The quote is "Mathematics is the supreme judge; from its decisions there is no appeal.", cited by "John Louis von Neumann" and "Tobias Dantzig". Please clarify or rectify this. By, the way the quotes page is superb too! Keep the good work up. We all are with you.

Well, not to take away anything, This is the best site for all us MATH lovers. I simply love cracking all these puzzles and questions and everything put up at 11:00 am. I mean, we all love cracking them. I would like to put up a suggestion. There should be a forum to post our own questions. The admin can then review it and, if standard it is up to the mark, can put it up one day FOR OTHERS to crack.
