Current affairs or general awareness or general knowledge section is as important as any other section in almost all government job competitive examinations. To improve our overall awareness there are lots of options like internet, newspapers, magazines, etc. However, there are very few options for exam specific preparation.
The most striking part of this section is that there cannot be any prescribed format to prepare oneself for it. Fortunately, there are some wonderful books which can help you to sail through these competitive examinations. I am listing the most trusted books on current affairs and general awareness below.
Manorama Yearbook 2013 with Free Encylopaedia Britannica CD ROM – This best seller has a long history of success. It is India's best General knowledge update covering almost everything that a student needs in competitive examinations – Purchase Online
This time I thought of giving you the crux of the whole article at the very beginning. See the formulae above and you will know what I am talking about.
We live in the age of information, and we must read extensively if we intend to be successful in our studies, or careers. Schools and colleges have discovered that courses in reading skills give enormous aid to students struggling under the heavier loads of today's scholastic programs. Young men and women trained in speed reading show distinct advantages over those who lack this kind of skill. For any competitive examination preparation, Speed Reading is an essential requirement. It is not only a must have skill for reading comprehension and verbal ability section but for the entire paper. Most of the examinations test your accuracy as well as speed.
How fast you can be?
Reading speed has no known theoretical limit. A speed of between 800 and 1200 words per minute (wpm) can comfortably be reached by permanent speed readers, without any constant practice and drilling. Reading speed varies according to the complexity of the reading material, type, face, print quality, grammar, style etc.
In CAT, MAT and other Competitive examinations like Bank PO, etc. you get questions where you need to find the last digit of numbers raised to large powers. It's almost impossible to calculate the values of such numbers manually and hence to find digit at their unit's place. Such problems can be solved using the concept commonly known as Cyclicity of Numbers. Here in this post I am explaining in details the concept of cyclicity and how it should be used for solving such problems.
Finding Last Digit of Any Number Raised to Any Power
This quantitative ability question was sent to me by Mr. Satish Kumar by mail. I generally answer the questions I get on email by directly replying to them. However, I thought this question is worth to be discussed with all QM readers. So here it goes -
I have a total of rs 1000. Item A costs rs 110,item B costs rs 90, item C costs rs 70 ,item D costs rs 40 and item E costs rs 45. For every item D that i purchase, I must also buy only 2 items of B. For every item A, I must buy one item of C. For every item E, I must also buy 2 of item D and one of item B. For every item purchased I earn 1000 points and for every rupee not spent I earn a penalty of 1500 points. My objective is to maximise the points I earn. What is the number of items that I purchase to maximise my points?
a) 13 b)14 c)15 d)16
"Give me the procedure to solve this with in 2-3 mins . It takes to much time 2 solve this for me." - Satish Kumar
Pay attention to Satish's problem and suggest time reduction techniques along with the solution to the above problem.
I would latter include the best answer(s), posted as comment, in the post itself.
Stress management is a big challenge in our day to day life. The academic system and the pedagogy is such, that it appears very early in our life cycle. The first thing which will come to our mind after hearing about exam is tension or stress.
Through this article I would like to share certain ideas, which I gathered over the time, to reduce stress and increase efficiency during examinations. The underlying ideas can also be applied to manage stress in other aspects of our life. I hope it will be beneficial for all the readers of QM, either directly or indirectly. The intention of writing this article is to help readers willing to increase their efficiency and perform better, by making the exam process less tiring and little more enjoyable.
How to Manage Stress before Examination?
- Take a piece of paper and list down the main reasons of your stress and anxiety. Next to each problem, write possible solutions. Take a break and discuss with your parents and (if possible) your teachers your fears and doubts
I remember back to early 2005 (before going for my post graduation), when I’d just started preparing for some competitive examination, that even though I had great ambitions, my knowledge, expertise, and confidence as a student was sorely lacking. My love for internet (as a source of information) made me stumble through various places on the web to know maths short cuts and quick maths tricks, but without much to gain from it.
Now, after having being there and facing it all as a student first and then as a facilitator (though I take good number of Quants classes for CAT aspirants, I would not liked to be called a tutor or a teacher. These titles should be reserved for people of great wisdom and learning) for over 4-5 years I felt I had a really good grip on things; and even then, there were many things I am still struggling with.
Now with the help of QuickerMaths.com, I want to create a platform, easily accessible to the student fraternity where they can get what they are looking for; at least things related to Quantitative Aptitude, Logical Reasoning, Analytical Reasoning and Critical Reasoning - a platform where you can ask questions and where you can give answers.
Let The Process Begin
I’m starting the process by posting below an interesting formula of the topic- time and work . The aim is to initiate the process of collaborative learning. So anyone who wants to make a difference can post a comment with any explanation, formula, shortcut, trick, solved examples, etc. on the same topic (Time and Work for this post). You can also help by sharing the information of this platform with your friends or anyone who wants to help others and learn from others in the process.
Time and Work Formula
I think the single most useful formula for the topic Time and Work is
N1H1D1E1W2 = N2H2D2E2W1
N1 and N2 = number of person
H1 and H2 = Hours worked by per person per day (assumed constant)
D1 and D2 = days
E1 and E2 = Efficiency
W1 and W2= Amount of work done
Consider this example to understand the applicability of this formula –
A piece of work can be done by 16 men in 8 days working 12 hours a day.How many men are needed to complete another work, which is three times the first one,in 24 days working 8 hours a day. The efficiency of the second group is half that of the first group?
N1H1D1E1W2 = N2H2D2E2W1
16*12*8*1*3 = N2*8*24*0.5*1
N2 = (16*12*8*1*3)/ (8*24*0.5*1) = 48
So number of men required is 48.
Note – you can remove anything from formula is not given in the question. For example if the question would have been –
“A piece of work can be done by 16 men in 8 days working 12 hours a day.How many men are needed to complete another work, which is three times the first one,in 24 days working 8 hours a day.”
The applicable formula would have been –
N1H1D1W2 = N2H2D2W1
Since nothing is mentioned about efficiency, we remove it from both sides.
Take the Link Challenge
Today I thought it might be fun to do a bit of a fun challenge.
The challenge is very simple – You have to find the websites, blogs, web pages, etc. linking to QuickerMaths.com (QM) or any of its post.
As your answers you have to just paste the URL (link) of the website or blog where you have seen QM link.
- The link might be a blogroll link like the one in the image below on fireup blog
2. Link within the text referring to QM. That could be because someone copied any post from QM and pasted it elsewhere.
The figure below shows an example of this on forum of www.caclubindia.com
- The link can be on a social networking site like facebook, orkut, etc. posted by you or someone else.
- The link could be a simple mention of the link - http://www.quickermaths.com or www.quickermaths.com or quickermaths.com
(But it should be a link and not simple text)
*You can even give the link of websites or blogs where you yourself have give QM’s link. When you posted the link doesn’t matter.
**Links present on QuickerMaths.com website will not be considered.
I assure you it will be a fun filled experience and your “googling” skills will improve a lot.

Try solving this questions which has appeared in CAT, GRE and GMAT papers and many other competitive examinations. So try your hands at this question from topic speed and distance. You can expect similar questions in competitive examinations.
Here is the Competitive Examination Question -
A thief escaped from police custody. Since he was a sprinter, he could run at a speed of 40 km/hr. The police realized it after 3 hr and started chasing him in the same direction at 50km/hr. The police had a dog, which could run at 60 km/hr. The dog would run to the thief and then return back to the police and then would turn back towards the thief. It kept on doing so till the police caught the thief. Find the total distance traveled by the dog in the direction of the thief?
Here are the options -
a) 720 km
b) 600 km
c) 660 km
d) 360 km
e) 230 km
I will provide the solution later. I urge everyone to try this. Please give explanation with your answers -
