images-1In recent years, CAT DI questions have moved away from the traditional graphical representation to the tabular one. Furthermore, the concepts involved are usually very basic and typical. Below is one such example, based on simple concept, testing your ability to interpret the given data.

In township TG Town, a bus operator Veeta Volvos is planning to launch operations. They did some preliminary survey on the number of people availing bus services during any given 4-hour window of the day (provided in the table).

mutual-fundDILR section has become a game changing section in the CAT. In the last two years this section has been the most difficult of all the three sections. Here is a DI set which will give a sneak peek at what can be expected in the CAT. This set comprises Type in the Answer(TITA) questions that have been a recent addition to the CAT.

Directions of question 1 to 4:

The investors can invest in four mutual funds – ICICI, SBI, Kotak and HDFC, to buy stocks of these four companies. Not all the investors invested in the mutual funds every month but when they did, each person invested Rs.100 to any one of the four mutual funds in a month, not necessarily the same fund every month.

For each of the four funds, the number of people who invested in each of October, November and December was either equal to or one greater or one lesser than their corresponding numbers in the previous month. For example, if ‘n’ investors invested in the ICICI fund in October, then the number of investors who invested in the ICICI fund in November can be ‘n – 1’, or ‘n’ or ‘n + 1’.

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.

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.
