Chocolate Maths Trick

Chocolate Maths Trick


Chocolate Maths Trick

Posted: 04 Apr 2011 06:46 AM PDT

You can do this little cute mathematics trick with your friends or girl-friends. This trick will be applicable for year 2011. Let me know if you like it.

Age by Chocolate - Mathematics Trick

Step 1. Choose the number of times a week that you would like to have chocolate between 1 and 10.

Step 2. Multiply this number by 2. Add 5. Multiply it by 50.

Step 3. If you have already had your birthday this year add 1761. If you haven't, add 1760.

Step 4. Now subtract the four digit year that you were born. You should end up with a three digit number.

The first digit is the number of times you like chocolate in the week.

The last two digits is your age!
Let me explain this to you using my date of birth as an example. You can try with yours.

Step 1. I choose to eat chocolate 6 times in a week. I love chocolates :)

Step 2. 6*2=12+5=17*50=850

Step 3. My birthdate is 5th April 1983 and my birthday in 2011 is yet to come. It will be there tomorrow ;)

So we have to add 1761 to 850 = 2611

Step 4. Subtracting 1984 from 2611 gives 627.

Here 6 is the number of time I would like to have chocolate and 27 is my age. Isn't it fun?

So for those who just want to have fun, go and do the trick with your pals. Those who want to exercise their grey cells, try and tell me what's going on here.

Books for Bank Exams

Books for Bank Exams


Books for Bank Exams

Posted: 30 Mar 2011 03:48 AM PDT

Bank exams, be it Bank PO (probationary officer) examination or Bank Clerical are not that difficult to crack as many people presume them to be. The main issue in this area is "vacancies : applicants" ratio. So instead of focusing on the toughness of the paper, one needs to concentrate on preparation. One has to surpass the scores of many others in order to stand a chance.

The first thing you need to know is the pattern of the exam. A written test for a bank exam consists of 2 parts, objective part and a descriptive part. The objective part consists of four sections namely, Verbal ability, Quantitative ability, Logical Reasoning and General Awareness/ Marketing aptitude. The exact pattern for a specific bank can be found in the 'acquaint yourself booklet' which you get when you apply for an exam

Many students requested me to recommend an all-in-one kind of book to refer for these examinations. Students are requested to practice from as many sources (online and offline) as possible to enable them to adapt to various kinds of papers. Practicing from multiple sources will broaden their horizon providing them flexibility and better ability to handle any kind of situation.
Although one book cannot be an end in itself, I am listing below a list of the best Bank Clerical and Bank PO examination books available. Instead of buying books at MRP from book stores, it would be wise to either buy them second hand (disadvantage of not getting the latest pattern) or through websites like flipkart.com (advantage of getting the latest editions at heavily discounted prices).

Best Bank PO and Bank Clerical Books

  • BANK PO & Specialist Officers Exam Guide - by Gkp (Publisher: G. K. Publishers (p) Ltd) – Purchase Online
  • Along with building the fundamentals on various topics covered under banking exams with the help of the book - BANK PO & Specialist Officers Exam Guide, a candidate needs to practice as much as possible. For preparation of Bank P.O. exams I suggest a book from the same publisher GKP. They publish an excellent collection of previous papers of Bank P.O. examinations of all major banks in the name of Previous Papers BANK P. O. Recruitment Exam - Purchase Online
  • Another good book for probationary officers' examination is "BPO : Bank Probationary Officers' Exam" by Ashok Mehta. For people preparing for this banking examination, I think it is an investment worth making. Purchase Online
  • For clerical recruitment - Bank Clerical Cadre Recruitment Exam by T. S. Jain - Purchase Online
  • For Bank I.T. officers examination preparation - Bank I. T. Officers : For All National & Private Sector Banks Exam Guide by Publisher: Ramesh Publishing House (2011) Editorial Board - Purchase Online

What is Lateral Thinking?

What is Lateral Thinking?


What is Lateral Thinking?

Posted: 27 Mar 2011 04:38 AM PDT

Lateral Thinking is a powerful method to use the unused potential of brain. This is originally propounded by Edward De Bono.  In this post various simple methods which can bring about lateral thinking capabilities in a reader are described. This post will surely help all CAT aspirants and future managers.

Lateral Thinking Methods or Skills-

There are a number of mental tools or methods that can be used to bring about lateral thinking. These include the following-

Random Entry: Choose an object at random, and associate that with the area you are thinking about. This is also called the method of focal objects.

For example imagine you are thinking about how to improve fireup.co.in. Choose an object at random from your room, you might see a spectacle. Spectacle helps to see things clearly. Perhaps this makes you think of embedding sound software that would readout the concepts and other website materials which would be a great help for visually impaired students.

Provocation: Provocation provokes us to look at things not as they are but as what they might be. We must change our perception in order to change directions and seek alternative solutions and questions what if, suppose what would happen, etc.. Make an idea that may not be direct solution to the problem but which moves thinking forward to a new place from where new ideas or solutions may be found.

Challenge: Simply challenge the way things have always been done or seen, or the way they are. This is done not to show there is anything wrong with the existing situation but simply to direct your perceptions to exploring outside the current area.

For example you could challenge coffee cups being produced with a handle. There is nothing wrong with coffee cups having handles so the challenge is a direction to explore without defending the status quo. The reason for the handle seems to be that the cup is often too hot to hold directly. Perhaps coffee cups could be made with insulated finger grips, or there could be separate coffee cup holders similar to beer holders.

Lateral thinking can be inculcated as propounded by Edward De Bono in his book “Lateral Thinking: Creativity Step By Step”. According to me and most of the people who have ever read this book it is a must read for anyone who is concerned with decision making and problem solving.  Purchase Online from Flipkart.com

Real life examples of lateral thinking

This question was asked to a candidate in a top MNC to elicit his true perception

Q – A man and his son are in a car crash. The man is killed and the son is taken to hospital gravely injured. When he gets there, the surgeon says “I can’t operate on this boy- he is my son!” How is this possible? [Surgeon is telling the truth, the boy don't have two fathers and he has no look alike]

This is an example of a quick assumption blocking the mind’s ability to explore alternatives. In this case the assumption is that the quintessential doctor is a male. If a candidate change his perception to allow for a female surgeon, then the answer is suddenly obvious, the surgeon is the boy’s mother.

You can find more than 50 examples here – lateral thinking questions.

Is 0.999…= 1?

Is 0.999…= 1?


Is 0.999…= 1?

Posted: 24 Mar 2011 07:49 AM PDT

Many a times we have made 0.999….= 1. But we always thought it's an approximation, they are not equal though.

It might be surprising for many of us to know that 0.999….. is actually EQUAL to the integer 1. It can be proved like this,

If x = 0.999..., then 10*x = 9.999... so by subtracting the first equation from the second, we get

9*x = 9.000...

Therefore, x=1.

Here's another proof - The number 0.1111... = 1/9, so if we multiply both sides by 9, we obtain 0.9999...=1.

So by similar arguments, every rational number with a terminating decimal expansion has another expansion that ends in a never-ending string of 9's. So, for instance, the rational 9/20 can be represented as 0.45 (the same as 0.35000...) or 0.44999...

General mathematical proof

Any rational number can be expressed in such a way that the digit in each place of a decimal expansion is associated with a positive or negative power of 10. The k-th place to the left of the decimal corresponds to the power 10^k. The k-th place to the right of the decimal corresponds to the power 10^(-k) or 1/10^k.

If the digits in each place are multiplied by their corresponding power of 10 and then added together, one obtains the real number that is represented by this decimal expansion.

So the decimal expansion 0.9999... actually represents the infinite sum

9/10 + 9/100 + 9/1000 + 9/10000 + ...

Using the formula for finding the sum of infinite G.P. series i.e. {a/(1-r)}, we get,

(9/10)/(1 - 1/10) = 1

Hence 0.999... equals 1.

There can be many other proofs. Math enthusiasts are welcome to suggest more proofs. Alternatively if you can prove that they not equal, please post.

Friends let me know your suggestions/feedback on the type of article I post on Quickermaths. You can also suggest me a topic to write. You can also write it yourself and send it across to me to be posted on QuickerMaths.

Brain Puzzle Question

Solve this interesting brain teaser or puzzle and exercise your mind.

Thief in the Jhootas' Club -  Brain Teaser

An expensive painting was stolen from the Jhootas' Club, but the CID is having a hard time identifying the culprit because every statement made by a member of the Jhootas' Club is false. Only four members visited the club on the day that the painting was stolen. This is what they told to the CID inspector Fredrick:

  • Anand: None of us took the painting. The painting was here when I left.
  • Bobby: I arrived second. The painting was already gone.
  • Chirantan: I was the third to arrive. The painting was here when I arrived.
  • Dinesh: Whoever stole the painting arrived before me. The painting was already gone.

Obviously neither Fredrick nor Daya could figure out who's the thief out of the four members of Jhootas' club. They requested you (an expert on such subjects) to solve this puzzle for them. According to you who out of these four liars stole the painting? Please explain to all of us.
