Um certo número X, formado por dois algarismos, é o quadrado de um número natural. Invertendo- se a ordem dos algarismos desse número, obtém-se um número ímpar. O valor absoluto da diferença entre os dois números (isto é, entre X e o número obtido pela inversão de seus algarismos) é o cubo de um número natural. A soma dos algarismos de X é, por conseguinte, igual a:

Um processo de escolha entre os n alunos de uma escola (n > 1) consiste no seguinte procedimento: os alunos são colocados em um círculo e inicia-se uma contagem da forma "zero, Um, zero, Um, zero, Um, ...". Cada vez que se diz "Um" o aluno correspondente é eliminado e sai do grupo. A contagem prossegue até que sobre um único aluno, que é o escolhido (por esse procedimento, portanto, sempre que o número de alunos no círculo inicial for igual a uma potência inteira de dois, o escolhido será o aluno que ocupava originalmente a primeira posição). Se há 192 alunos no círculo inicial, a posição neste círculo que é ocupada pelo aluno escolhido é a de número:

Cinco colegas foram a um parque de diversões e um deles entrou sem pagar. Apanhados por um funcionário do parque, que queria saber qual deles entrou sem pagar, eles informaram:
– "Não fui eu, nem o Manuel", disse Marcos.
– "Foi o Manuel ou a Maria", disse Mário.
– "Foi a Mara", disse Manuel.
– "O Mário está mentindo", disse Mara.
– "Foi a Mara ou o Marcos", disse Maria.
Sabendo-se que um e somente um dos cinco colegas mentiu, conclui-se logicamente que quem entrou sem pagar foi:

AN INTERVIEW WITH A FUND LEADER
Question: Do you invest in pure Internet companies only? Or, in other words, companies with a .com at the end of their name?
Chris Bell: No. We invest in three distinct market sectors and the percentage of the portfolio in each changes as our view alters. Currently, around 45% of the portfolio is in the shares of pure Internet companies. Last summer we had under 30% in this sector of the market. There was a big sell-off of pure Internet companies last summer because of concern about US interest rates. We saw the share prices of some of the bellwethers of the sector, such as Amazon.com, halving. Come September we thought the sell off had become too big and began to increase our weighting in this area of the market.
The second area we invest in is technology infrastructure. Our holdings include companies such as Cisco Systems, Intel and Oracle. These companies develop systems to speed up the functioning of the Internet and 45% of the portfolio is in this area of the market.
The other 10% of the portfolio is invested in Internet-related companies. This can be any company we feel will benefit from the growth of the Internet.
According to the interviewee, US interest rates

STOCK OPTIONS
Twenty years ago, the biggest component of executive compensation was cash, in the form of salaries and bonuses. Stock options were just a footnote. Now the reverse is true. With astounding speed, stock option grants have come to dominate the pay - and often the wealth - of top executives throughout the United States. Last year, Jack Welch's unexercised GE options were valued at more than $260 million. Intel CEO Craig Barrett's were worth more than $100 million. Michael Eisner exercised 22 million options on Disney stock in 1988 alone, netting more than a half-billion dollars. In total, U.S. executives hold unexercised options worth tens of billions of dollars.
