(A) LINEAR SEQUENCING : Certain entities are arranged in a row as per the instructions/conditions given in the
question. The statements/conditions provide information about the position of these entities, with respect to other
entities or with respect to positions in the row. Proper care should be taken when interpreting the details mentioned in
(B) SEATING ARRANGEMENT: Questions of this type, describe people seated around a table (which could be of any
regular shape – circular, rectangular, square, hexagonal, etc) or in a row or in rows and columns. If the persons are
seated in a row, the problem reduces to one on linear sequencing, but if they are seated around a table, the shape of the
table, the number of people on each side of the table (in the case of a rectangular or hexagonal table) or around a
circular table, and other details should be considered.
(C) DISTRIBUTION/DOUBLE LINE-UP: In such problems, various elements under certain groups are matched and they
form certain combinations with the elements in the other groups. Sometimes, a grid is formed and with the help of ‘’
and ‘’ in various rows and columns, the combinations between the elements can be formed. In solving such
questions, the student is better off drawing a table where groups are written in columns. The table should then be filled
up using the information provided and the required analysis should be done.
(D) SELECTIONS: In these type of problems, a certain number of people (or things) have to be selected out of a group,
conforming to the conditions mentioned. Many a time, these conditions consist of connectives. For example, in a
condition like “If A is selected, then B is not selected”, you have to consider the implications and verify the choices.
The correct answer choice should not violate any of the given conditions.
(E) ORDERING & SEQUENCING: In these types of problems, some people or things are compared with each other in
terms of a measurable parameter (like height, weight, age, speed, marks, etc,). Also, in certain questions, some people
or things are arranged in a particular sequence.
(F) ROUTES & NETWORKS: Usually in such problems, certain places are connected with each other with the help of oneway
or two-way roads. When solving these kinds of problems, the student should draw a diagram of the network.
While tracing routes, the focus should be on the direction of the incoming & the outgoing arrow marks.
(G) BINARY LOGIC: Such types of questions are gaining popularity in various MBA entrance
exams and also in Campus Recruitment aptitude tests. In these types of questions, we may encounter some people (say
three), each belonging to a different race/type/tribe/variety, namely (i) Truth-tellers, (ii) Liars, and (iii) Alternators. Truth tellers
are those who always tell the truth, liars always speak lies and the alternators alternate between the truth and lies,
in any order. Some questions may consist of people belonging to the same race. For example, each of the three persons is
an alternator. While tackling problems which consist of a person belonging to a different type out of the three types, you
should look for two contradicting statements and then assume one of them to be true and continue making the arrangement.
Alternately, one person can be assumed to be the truth-teller and an arrangement should be made by verifying the
status of each statement. If the arrangement gives rise to a contradiction or is in disagreement with the instructions, it will
mean that our initial assumption regarding the truth-teller is wrong. Hence, we will then assume the second person to be
the truth-teller, and so on.
(H) CUBES: There are various categories of questions which are asked based on cubes : (i) when the number of cuts made
to the cube is given and the maximum number of identical pieces is to be found; (ii) when the number of identical
