Sitting arrangement is one of the popular topics of LRDI section for any competitive exam. The best thing about this topic is that you don’t need to apply any out of the box thinking but to process and write down all the information that is given to solve the questions. Sometimes you will feel that given information is not enough to complete the arrangements but remember your job is to solve the questions not to complete the arrangement.

Here I am giving you some sets of linear and circular arrangements, try to solve them and then match your answers with the given solution.

Direction for question number 1 to 4: Four couples A,B,C,D,E,F,G and H are sitting together on a bench facing towards north not necessarily in the same order. It is also known that

I. A,C,E,G are females who are sitting immediate left of their husbands.
II. G is sitting immediate right of H who is sitting three places away to the left of C.
III. A is sitting five places to the left of B who is sitting 3rd from extreme right.

Out of Context questions are known for their tendency to make you see identical stars (those in the picture are star sheep) in broad daylight!

Ready to mull over these?

Four sentences are given below; three of them when arranged in a logical sequence form a coherent paragraph, but one of them does not fit into the sequence. Pick the sentence that does not fit into the sequence.

A. Entrepreneurs face the hassle of managing their taxes efficiently.
B. Some entrepreneurs have sought professional help to manage taxes.
C. Obscure regulations have the capacity to throttle most entrepreneurs.

No no….don’t get it wrong.
Here, we are talking about one of the interesting topics in CAT-preparation (and all others MBA entrance tests also) i.e. Circular motion – a small but very important part of a broader topic: Time, Speed and Distance.
We are specifically focusing here on the meetings of the runners on a circular track (or any closed track for that matter). As we go on, I will post some questions and in the explanation I’ll discuss few important concepts that’ll remain with you at the end of this session.

The sentences given in the question, when properly sequenced, form a coherent paragraph. Each sentence is labeled with a letter. Choose the most logical order of sentences from the given choices to construct a coherent paragraph.

A. It conceived of the gods as blissful and immortal, yet material, beings made of atoms, inhabiting the empty spaces between worlds in the vastness of infinite space, too far away from the earth to have any interest in what man was doing.
B. In modern popular usage, an epicure is a connoisseur of the arts of life and the refinements of sensual pleasures, especially of good food and drink, attributable to a misunderstanding of the Epicurean doctrine, as promulgated by Christian polemicists.
C. It can be argued that the philosophy is atheistic on a practical level, but avoids the charge of Atheism on the theoretical level, thus avoiding the fate of Socrates, who was tried and executed for the Atheism of his beliefs.
D. Epicureanism emphasizes the neutrality of the gods and their non-interference with human lives, although it did not deny the existence of gods, despite some tendencies towards Atheism.

similartrianglesSimilar triangles present one of the biggest tools students have to solve many geometry questions. And yet, whenever the opportunity arises, the students often fail to spot the similarity between two triangles. Sometime they spot the similarity but fail to apply the ratios correctly. Today we will start with some familiar cases in which we apply similarity of triangles and then move on to some tricky and difficult cases. We hope that after solving all these problems, you’ll not have any issue in spotting and solving similarity.

In practical scenario, we always prove that two triangles are similar by proving that their corresponding angles are equal. For example, look at the very simple figure below:

two similar triangles

If you can prove that $\angle BAC$ = $\angle QPR$ and $\angle ABC$ = $\angle PQR$ then $\triangle ABC$ and $\triangle PQR$ are similar. In which case the ratios of the corresponding sides are equal. The best way to write the ratio of the sides is to write both the triangles in the order of the angle which are equal (for example here $\angle A$ = $\angle P$, $\angle B$ = $\angle Q$ and $\angle C$ = $\angle R$ so write ABC and PQR only) and then write the ratio by picking same corresponding points from the two written triangles. Therefore,

The passage given below is followed by a set of questions. Choose the best answer to each question.

As I said before, I do not think that the real reason why people accept religion has anything to do with argumentation. They accept religion on emotional grounds. One is often told that it is a very wrong thing to attack religion, because religion makes men virtuous. So I am told; I have not noticed it. You know, of course, the parody of that argument in Samuel Butler’s book, Erewhon Revisited. You will remember that in Erewhon there is a certain Higgs who arrives in a remote country, and after spending some time there he escapes from that country in a balloon. Twenty years later he comes back to that country and finds a new religion in which he is worshiped under the name of the “Sun Child,” and it is said that he ascended to heaven. He finds that the Feast of the Ascension is about to be celebrated, and he hears Professors Heroditus and Panopticon say to each other that they never set eyes on the man Higgs, and they hope they never will; but they are the high priests of the religion of the Sun Child. He is very indignant, and he comes up to them, and he says, “I am going to expose all this humbug and tell the people of Erewhon that it was only I, the man Higgs, and I went up in a balloon.” He was told, “You must not do that, because all the morals of this country are bound round this myth, and if they once know that you did not ascend into Heaven they will all become wicked”; and so he is persuaded of that and he goes quietly away.

As the name suggests, data interpretation is all about logical interpretation of the given data and answering questions. Data interpretation carries the same weightage in third section of CAT as reading comprehension in verbal section or geometry and algebra in quant section. For the past two years (CAT 2014 & CAT 2015), CAT carries approximately 20 questions on data interpretation. If you haven’t been serious about this topic till now, there is never a better day than today to start!

Data can be represented in many ways, some of the most common ways are tables, bar graphs, Line Graphs, paragraphs, pie charts etc… This article will focus on LINE GRAPHS and will introduce you with the most basic aspects of a line graph.

line graph basic example

above is one of the basic example of a line graph and its various component are as follows:

Title : The title of the graph tells us what the graph is about
Label : Horizontal and vertical labels tell us about type of the data
Axis : X and Y axises tell us about the unit of the data.
Dots : Dots on the line graph tell us combination of X and Y axis data.
Line : The blue line connecting the dots in the above graph gives a visual representation of the data, and its variation.

Read the passage given below and answer the questions that follow:

There is nothing easy about the adoption of cloud computing. It demands new information-technology (IT) and developer skill sets. It also challenges organizational structure and work practice. But that does not mean, as Bruce Schneier says, that “it’s complicated” or a “maybe”. Companies should make the adoption of the cloud a strategic imperative because it is a vastly superior way to deliver reliable, secure, scalable computing—which is needed to fuel business.

Mr Schneier highlights the potential risks of the cloud, but fails to account for the risk of not adopting it. Businesses exist to deliver value while managing risk. And the broad adoption of cloud computing will dramatically decrease risk and offer incredible opportunities to firms that seek competitive advantage. Mr Schneier neglects to mention the manifest risk inherent in the status quo: a legacy mindset born of well-founded fears. Today’s IT infrastructure is a Swiss cheese of vulnerable networks, operating systems and applications developed before the internet. It is difficult and expensive to keep running—and easy to penetrate. In 2014 Verizon reported more than 2,100 data breaches. The FBI has claimed that every major American company has been compromised by the Chinese—whether they realized it or not. Against this backdrop, it is rational for IT staff to seek greater control by locking down networks and computers, and by prohibiting the use of the cloud.
