&lt;div style=&quot;text-align: justify;&quot;&gt;
Albert e Bernard tornaram-se amigos de Cheryl, e eles querem saber quando é o aniversário dela. Cheryl dá a eles 10 datas possíveis.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
15 de maio&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
16 de maio&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
19 de maio&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
17 de junho&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
18 de junho &lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
14 de julho&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
16 de julho &amp;nbsp; &lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
14 de agosto&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
15 de agosto&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
17 de agosto&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Então Cheryl conta para Albert e Bernard, separadamente, o mês e o dia do seu aniversário respectivamente.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Albert: Eu não sei quando é o aniversário de Cheryl, mas eu também sei que Bernard não sabe.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Bernard: Inicialmente eu não sabia quando é, mas agora eu sei.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Albert: Então eu também sei quando é o aniversário de Cheryl!&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
E aí, quando é o aniversário de Cheryl?&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;h3 style=&quot;text-align: justify;&quot;&gt;
Enunciado em inglês&lt;/h3&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Albert and Bernard just become friends with Cheryl, and they want to know when her birthday is.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Cheryl gives them a list of possible dates.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
May 15&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
May 16&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
May 19&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
June 17&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
June 18&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
July 14&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
July 16&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
August 14&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
August 15&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
August 17&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Cheryl then tells Albert and Bernard separately the month and the day of her birthday respectively.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Albert: I don&#39;t know when Cheryl&#39;s birthday is, but I know that Bernard does not know too.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Bernard: At first I don&#39;t know when Cheryl&#39;s birthday is, but I know now.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Albert: Then I also know when Cheryl&#39;s birthday is.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
So when is Cheryl&#39;s birthday?&lt;/div&gt;</content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/9040250137227687592/posts/default/8613085614274043663'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/9040250137227687592/posts/default/8613085614274043663'/><link rel='alternate' type='text/html' href='http://matematicario.blogspot.com/2015/04/problema-de-logica-viral-de-singapura.html' title='Problema de Lógica Viral de Singapura'/><author><name>Unknown</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://img.youtube.com/vi/nKQxTG4VC-w/default.jpg" height="72" width="72"/></entry><entry><id>tag:blogger.com,1999:blog-9040250137227687592.post-7027769436950837854</id><published>2015-04-11T04:56:00.001-07:00</published><updated>2016-04-02T18:10:06.629-07:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="Aritmética"/><category scheme="http://www.blogger.com/atom/ns#" term="Curiosidades Matemáticas"/><category scheme="http://www.blogger.com/atom/ns#" term="Desafios"/><title type='text'>Desafio de raciocínio lógico: você consegue resolver?</title><content type='html'>&lt;div class=&quot;v-wrap&quot;&gt;&lt;iframe allowfullscreen=&quot;&quot; frameborder=&quot;0&quot; height=&quot;340&quot; src=&quot;http://www.youtube.com/embed/0tsvCYwzyfo&quot; width=&quot;565&quot;&gt;&lt;/iframe&gt;&lt;/div&gt;&lt;img border=&quot;0&quot; height=&quot;0&quot; src=&quot;http://i2.ytimg.com/vi/0tsvCYwzyfo/0.jpg&quot; width=&quot;0&quot; /&gt;
Saiu na página do 9GAG esse desafio e deixou muita gente pensativa. Aqui eu mostro a minha solução.

Esse problema, um exercício de porcentagem, é um tanto paradoxal. Em uma sala onde estão 100 pessoas, sabe-se que 99% são homens. Quantos homens devem sair para que a porcentagem de homens na sala passe a ser 98%?&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://matematicario.blogspot.com/feeds/3215126164914080107/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://matematicario.blogspot.com/2014/05/problema-do-paradoxo-da-porcentagem.html#comment-form' title='1 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/9040250137227687592/posts/default/3215126164914080107'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/9040250137227687592/posts/default/3215126164914080107'/><link rel='alternate' type='text/html' href='http://matematicario.blogspot.com/2014/05/problema-do-paradoxo-da-porcentagem.html' title='Problema do paradoxo da porcentagem'/><author><name>Unknown</name><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://img.youtube.com/vi/EMjZiijiVuw/default.jpg" height="72" width="72"/><thr:total>1</thr:total></entry><entry><id>tag:blogger.com,1999:blog-9040250137227687592.post-6107410576731090637</id><published>2014-05-23T07:54:00.001-07:00</published><updated>2016-04-03T08:32:28.475-07:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="Aritmética"/><category scheme="http://www.blogger.com/atom/ns#" term="Curiosidades Matemáticas"/><category scheme="http://www.blogger.com/atom/ns#" term="Desafios"/><title type='text'>80% das pessoas erram o valor desta expressão numérica</title><content type='html'>&lt;div class=&quot;v-wrap&quot;&gt;&lt;iframe allowfullscreen=&quot;&quot; frameborder=&quot;0&quot; height=&quot;340&quot; src=&quot;http://www.youtube.com/embed/ZtD_3VA4yBI&quot; width=&quot;565&quot;&gt;&lt;/iframe&gt;&lt;/div&gt;&lt;img border=&quot;0&quot; height=&quot;0&quot; src=&quot;http://i2.ytimg.com/vi/ZtD_3VA4yBI/0.jpg&quot; width=&quot;0&quot; /&gt;
