YungMillionaire:
I will like to set up a Nairaland Math/Science club. I see more than a few talents on this thread. Even the textbook warriors have their own little place in my heart Lets bring all these talents together and share ideas, solve problems and have math fun on this forum.

Lol@ textbook warriors. You ehn. Well, you may be wrong. I don't believe in lacram lapour. I like application based stuffs.
Nice idea you have bro. A similar thread already exist on this forum. You can go in there to contribute your quota or paste your questions there. This is the thread
https://www.nairaland.com/1147658/nairaland-mathematics-clinic

CACAWA:
Excellent.

This is what maths should look like.

God bless you

Abi now. God bless you too.

yorex2011:

Weldone bro. I guess this is the kind of intelligence akinaphysicist, Godisbiafran and yungmillionaire meant

AkinPhysicist:
Clap 4 yourself. Using my 'wuru wuru' method: No pen and paper needed. And it took me less than a minute. Try it. Its good for your brain.


By the way - we already hashed this out yesterday. Keep up. See this:

The ideal thing is to first of all use the wuru wuru method now before setting out to solve so that one will have an idea of what the answer should look like. It is a smart way of reasoning. However, you are failing to get my points. Sometimes, the answer set may span a larger loop and because of that we need to set out standard ways of resolving such questions for the sake of other people watching( same thing cacawa was trying to communicate to you). You be chairman now. Who would doubt your ability of being able to solve such question.

GodIsBiafran:
akinphysicist - yes but am not sure of the naturalwaves guy. He has not been fully vetted yet. Right now he is just making noise up and down.

. You guys are so hilarious. It is not a competition now and I have nothing to prove to you. I come here anytime I can. I contribute my own quota if I can and learn from people as well. You guys should learn how to make good intelligent convos online. Again, my dear, I have nothing to prove to you o.

AkinPhysicist:
Because its a fun out of the box kind of way of doing it


Good. Children can teach you are lot about imagination and creativity. Be a child once in a while and you will see things differently.

So? - as long as the child knows the answer has to be positive definite so he starts from zero instead of negative infinity. This child has learn far more mathematics than the people subtracting 2 from both sides to see what happens. Whatever its worth the child probably knows the subtraction method too.


It would be trial and error if I didn't know where to start and were to stop. See my post above about the creative child who knows where to start counting from. That is the key. There are quite a few advanced mathematics techniques that employ spanning a limited space to find element or elements that fulfill a particular restraint. This is what I did here. If you are wise you will learn.



If you truly believe I cannot solve this problem in the normal (school textbook way) then why are you engaging me in this conversation?

You are very funny. You just have a way of evading things even though you know what I was talking about. Your evasive techniques shows how intelligent you are. Moreover, why would I think that you won't be able to solve the question? Like I said, it is for the benefit of others watching as well. No hard feelings and stop dribbling up and down joor.

skillful01:
akinphysicist and naturalwaves,you guy 've got pure intellect.

Thank you bro. Since Akinphysicist has decided to dance in circles and not provide a suitable solution to the question nor provide an alternative method that is more acceptable, let me solve it through a way that is devoid of wuruwuru and trial by error like he did for the benefits of secondary school students and others viewing the thread. See solution attached below.

StarBukola:
ohh for me?? I don't knw what to say

Yeah, sure!

AkinPhysicist:
Uggh! Not again. These people and their wahala Assumptions are part of mathematics. Look it up. If an integer solution exists you will find it. If you don't find it then you will KNOW that an integer solution does not exist. This itself is KNOWLEDGE you did not have prior to the count test. In the absence of an integer solution, then a more general approach can then be used to solve the problem.

Why would you make an assumption when there is a legitimate way to go about it without assumption? What you did is not different from a child being asked to solve for X in 2+X=6 and then you start testing 1,2,3 etc to see which one will give 6. That is trial method and it is demeaning for someone of your calibre. Provide a suitable solution that is devoid of trial and error.

AkinPhysicist:
If you don't understand then ask questions. Here is my response to someone who was wise enough to seek clarification:

Kelvinreality - after giving Cacawe all night to answer the question above, I have concluded he is incapable of basic logic. Here is the explanation:

x^1/2 + (x+15)^1/2 = 15. If an integer solution exist, then you can obtain it by counting. Here is how it works.

Let a = x^1/2 and b= (x+15)^1/2 so the eq. becomes a + b =15. So choose a pair of integer a and b whose sum gives you 15. However, NOT all pairs qualify because a^2 has to be equal to b^2 - 15 (since both have to be equal to x). So all you have to do is count from 0 to 15 to see which pair qualifies. Clearly any pair with a from 0 to 5 fails because in this case a^2 is clearly less than b^2 -15. You don't even need to do any calculation - all you need to know is if b^2 -15 is greater (or smaller) than or equal to a^2. If its equal then you have your solution. No calculator required. Nothing. Just basic logic of counting.

You are so funny bro. How will you start up a mathematical solution with " If an integer solution exists". That's not right at all. Okay, what if an integer solution does not exist? What universally accepted principle are you going to use for it? Show it! You can't be substituting unknowns with integers based on logic except incase of objectives or something that requires a fast answer and thaat is not the case here.

StarBukola:
when we could have split the the money,70 for me 30/for u

Hahahaha. Very funny. Don't worry, will give you 90.

AkinPhysicist:
Archaic and unacceptable? This is not a thread about mathematical etiquette. The OP wanted creative/original solution to a problem. And I supplied it. What Okocha did to Khan (the German goalkeeper) was considered disrespectful but football like math does not give a damn who feels disrespected. The question you should ask yourself is simple:- did I provide a solution for the problem? If then answers is yes, then don't waste your time pontificating.

Your solution lacks a mathematical pathway. When you solve things here, you should consider other viewers as well. A good example was the one you solved for the first puzzle, that was better. At least, people can follow up that solution unlike the second one you posted.

StarBukola:
Where is naturalwaves now

I did not see the thread on time. When I got in, it had been solved.

CACAWA:
Abi o.

People should realise that a lot of things happen in here and people learn. We have secondary school students and university students that can learn as well. Everyone know that the solution to that question you posted can be done by mere looking but a good solution is required. The moment I saw his explained solution, I was so disappointed.

You can insult someone for being lazy, not working when others are working or not being serious but body features are not things that can be determined by the carrier. We all have preferences but that is not enough reason to insult a person. When people are not endowed, it is not their making, they just find themselves that way. People should learn to be reasonable.
ps: I am not on the small side but the way girls insult and make fun of guys that are is unreasonable.

YungMillionaire:
My guy calm down. You are being unreasonable. For you to think am Akin is absurd. Anyway, here is my thinking: You have a problem and you seek the easiest solution is called being clever. Akin counted. And found a solution. Of course counting by its nature can only give you an INTEGER solution. He did not say that was the ONLY solution - he told you "put 49 for X and see what happens." I am following this thread closely because its mine. And since 49 satisfied the equation Akin was correct. That is original and clever - that's the point I was trying to make. I never said you are not intelligent, I just think Akin is more intelligent than you, no offence.

You are being unnecessarily childish and sentimental on this thread. The Akin guy should have known that such solving methods is archaic and unacceptable in maths. How can he use trial and error method to solve that question? What if the solution is something like 120 or more? Will he keep on counting till he gets there? He knows exactly what CACAWA wants but decides to be clever by half and you are just buttlicking him and trolling cacawa unnecessarily.

peacettw:
Lol. Anytime I find a puzzle whose solution is attached to a prize. I do the following.

1. Copy the entire puzzle and paste in Google search

And voila, the answer is back in a less than a minute enabling me to solve this puzzle and win the prize way ahead of my competitors.

This is the link to the solution already solved in 2001.

http://mathforum.org/library/drmath/view/57511.html

Same puzzle, different variables. Notice the winner of this puzzle used exactly the same steps.


You are welcome.

@op ,Next time, find the time to create your own puzzles otherwise your account will be drained faster than the time it will take to solve the puzzle.

It is not necessarily true. Do not say what you are not sure of. How did you know he cheated? Moreover, the puzzle is extremely easy. It did not take me 60 seconds to solve. I only set out 2 equations and the answers were out so fast. This is normal JSS2/JSS1 word problems involving simultaneous equations. The fact that you cheat does not mean that everyone does. What's the fun in cheating? huh?

YungMillionaire:
As someone who is a big fan of pure reasoning and logic, I have decided that once a year I will offer 10 000 naira to any Nairalander who is able to solve a unique math problem. The goal is to appreciate people who show a unique ability for clear thinking and originality. This year the award will go to the first Nlander to solve this problem:
A farmer has a small farm of chickens and rabbits. There are 28 heads in total and 80 legs in total. By using simple logic and reasoning find out how many chickens he has and how many rabbits he has. You have to SHOW YOUR WORK. IT IS NOT ENOUGH TO GET THE RIGHT ANSWER, YOU HAVE TO SHOW HOW (WITHOUT USING FORMAL MATHEMATICS – YOU CAN HOWEVER USE FORMAL MATH TO SHOW THAT YOUR REASONING IS CORRECT) YOU SOLVE IT USING PURE REASONING AND LOGIC. IF YOU SOLVE IT USING FORMAL MATHETICS YOU WILL NOT GET THE PRIZE AWARD. IF YOU ARE THE FIRST TO SOLVE THIS PROBLEM IN THE MANNER DESCRIBED ALL YOU HAVE TO DO IS PM ME YOUR BANK DETAILS AND YOU GET YOUR 10,000 NAIRA.

Good luck.
YungMill

I came late but this was a very cheap one. Did not even take me a minute to solve. If you have tougher ones, please paste them and mention me.

nurey:
the only station i trust above any station in Nigeria is

MRS if i now intend to rate them in 90% of their filling station scattered around lagos, their Litre is always closer to the real deal than others

MRS
TOTAL
NNPC
FORTE
unfortunately i have not bought fuel from other stations apart from MRS for over 6months.

From the responses given, we can conclude that
1. A couple of filling stations have accurate pumps .
2. Apart from having accurate pumps, NORTHWEST filling station, VGC is the best filling station in Lagos if not Nigeria.

urtchmoni:
(Northwest Petrol Station) Ajah just before VGC...is the best in town...just try and see. Northwest is taking over Patrol Biz. Learnt they use only B.Sc holders as pump attendants. hmm love there packaging.

If you go behind the filling station, you will see that they also have a good looking hostel for the attendants. Moreover, during the fuel issue, Northwest never increased fuel price for once. It appeared more like a charity than business at that time and their queue was almost as long as Lagos to Ibadan.Lol. The management should keep it up. The attendants are so neat and eloquent. The only thing they need to improve on is the speed of transaction.

kfrosh:
As in ehn! I was already thinking like, lemme quickly go check the price of this perfume with the hype created here probably it will be my next target as I am a perfume freak. I see the price shock, na so I change my mind. #wicked

The funny thing about perfumes is sthat it is not usually the price that make a good one. It is more about the uniqueness of the frangrance. Like my own perfumes Casablanca( white bottle) is not even up to 2K but if you lay down thousands of perfume, none can smell like it. You know there is this general category of perfumes that just smell normal like regular perfumes while few have a unique smell. Talking about expensive perfumes, some are expensive because of what was used in making them and how scarce it is. Some can say a certain back of oak tree or something was part of the ingredients or a soaked flower from Cuba or the bahamas etc. The funny thing thing is that you may not even like it going by the scent. Some other perfumes are expensive because of the quality of the bottle and not necessarily the content. If you're looking out for a long lasting perfume, make sure it is oil based. If you put an oiled based perfume on your palms, it will be oily in a way. The more oily a perfume is, the longer it lasts. Some can even last for up to 1 month when it touches a cloth unlike those other perfumes you put on your palms that undergo effervescence like methylated spirit.

StarBukola:
yes now is it bad??plus I have some really smart friend, I don't move with olodo

cool. You know people have different things to offer. The so called "olodos" may be better in other regards. I think the most important thing is not being negatively influenced.

StarBukola:
amam mention from now on

No wahala.

StarBukola:
I have a thing for smart people, I keep them.closer the might come in handy some times

You keep them close just because they could be handy at any time? hmmm

StarBukola:
don't tell u don't talk dirty ooo.... C'mom I dare u to talk

. My mummy is on Nairaland.

StarBukola:
Since works and no play makes? Naturalwaves come in

StarBukola:
makes u a smarty pants

. I guess this is your own edition of the quote.

ezehisaac:
I just wish I could have a direct access to these above mentioned perfumes

Like Creed-Aventus right? . That perfume is betwen 148k to 160k ooo.

StarBukola:
I tot naturalwaves reply to only puzzles

Hahahahaha . No use laugh kill me o. You know what they say about " all work and no play"?

StarBukola:

? Hi

tosyne2much:
A male ni ooooo.. We call him ashawo guy

BTW, I'm yet to see your mail bro

lol@ashewo boy. why? cos it smells soft like a powder or what? Sent.

tosyne2much:
That's what my friend uses too.. I like the unique fragrance sha

Wow, col. male or female? Most people always end up taking my bottle, making me go buy another one.

rudestmcblaze:
I've studied Mou very well and I knw that he was looking forward to hurting Pep. I think he would have had a better chance of wining if he had played a 4-5-1 with a mildfield trio of Carrick, Herrera and Mhki and flanked by Lingard and Young and Rashford as a centre forward. Fellaini slows the pace of the game, I dunno why Mou keeps fielding him bt I'm sure he is the manager and he knws best. Looking forward to our europa league success...GGMU

@bolded, Mourinho and every great coach were once a mere spectator like us. You may make a better coach in future. So, it is not totally correct to say someone knows best just because he is the coach.#justsaying

MOU actually planned and came for a draw and if Man U scores, good! But he was not keen about that. I think the perimeter fencing type of formation he used was superb enough to cut the bites from Manchester city. The aim of MOU was never to go for an outright win in that game because in the course of mounting pressure on the opposition, their own defence will subsequently give in. He used almost a similar tactic for chelsea in just another form with better players and few more options. Luckily enough, the attack made good use of 2 of the few chances they had and Man U was able to beat Chelsea.

Moreover, Mourinho's records still stand. Since Mourinho started coaching, no coach has ever beaten him twice in one season What that means is that he does his home work well. Even if things do not go well first time, he will make very good adjustment before the second meeting. His reaction is always top notch!
