CRT Analytical and Logical Reasoning

Code

A code is a system of words, letters, numbers or symbols that represent a message or record information secretly or in a shorter form.

Arithmetical operation

As the name suggests, here the input consists of certain numbers. The subsequent steps are obtained by taking the number of the input and performing some arithmetical operations on them

Simple or Direct Analogy

Following example will explain the concept of Simple or Direct Analogy:Earth is related to Axis in the same way as wheel is related to Hub. Here the first rotates about the second.

Arranging

Here the inputs are arranged as per a particular order. For example, number can be arranged as per increasing or decreasing order while word can be arranged as per the order in which they appear in dictionary.

Relationship based on meaning

Identify the given questions odd one out depend on meaning of the words.

Analogy based on Numbers

In these type of Questions a candidate is required to find out the relationship between given groups of numbers related to each other in some way

Analogy based on Alphabet

In these type of Questions a candidate is required to find out the relationship between two given groups of letters related to each other in some way and then choose either a letter group or pair consisting of similarly related letter groups.

Substitution Coding

In this type of coding, different objects are assigned code names.

Shifting

In this type of problems, elements of the given input are shifted (that is, their positions are changed) as per some logic

Selecting a similar word

In this type of questions, a group of three/four inter related words is given. Candidate is required to select a word from the given alternatives that is similar to the given words and hence belongs to the same group.

Input and Output

In this type of questions, a sequence, either in form of a sentence or in numeric form is given. This sequence is popularly known as input. The input is followed by steps of rearrangement to give sequential output. The candidate is required to understand the pattern in the given arrangement and then determine the desired output step, according as asked in the questions.

Classification

In this type of questions, all the options except one are belonging to same category. We have to identify which one is different from the rest

Mixed letter coding

In this type of questions, three or more sentences are given in the coded language and the code for a particular word is asked. To find the code for the particular word, pickup two sentences bearing a common word and the common code word will mean that word. Proceeding in similar manner, we can be determined a particular code word for each word of given sentences.

Coding

It is a method of transmitting a message between the sender and the receiver such that no other person can understand the message.

Decoding

It is a method to find the meaning of something that has written in code.

Selecting the Analogies Pair

It is a relation between two words of pair.Sonnet: Poem::Murder:Crime.Clearly Sonnet is a part of Poem, similarly murder is one of the type of Crime.

Functional relationship

It is type of certain functional relationship.

Dictionary Test

Mental ability questions in verbal reasoning are common in many competitive exams and entrance exams. Almost every verbal reasoning test contains questions on alphabetical series. The types of questions in alphabet test are as alphabetic series or alphanumeric series or continuous pattern series.

Even, odd or prime number relationship

One of the number logic vary with odd or even number concept

Direction Sense Test

Questions based on directions are generally asked in each examination. Hence in order to give correct answer, a candidate must have full knowledge about directions. There are four main directions: North, South, East and west

Ranking Test

The position of a thing/person etc. in a definite order is called as 'Rank'.

Questions on interest

The questions on simple and compound interest will require you to apply various formulas that you have studied as a part of your high school curriculum.

Ratio and proportion

The ratio and proportion questions under Arithmetic Reasoning can be solved by using simple formulas.

Numbers

These particular questions will examine your knowledge of whole numbers, real numbers, fractions, decimals and imaginary numbers. These questions will also evaluate your knowledge of certain basic Arithmetic formulas.

Ages

These problems deal with the age related questions.

Basic concepts of Arithmetic

These problems will require you to use preliminary concepts of Arithmetic like addition, subtraction, division and multiplication.

Concepts of percentages

These problems will require you to use your knowledge of percentages, cost price, sale price, discount etc.

Arithmetical Reasoning

These questions are designed to test your ability to use mathematics to solve various problems that may be found in real life — in other words, math word problems.

Clockwise direction

When a point moves in the direction of hands of clock, then it can be said that the point is moving in CW direction.

Anticlockwise direction

When a point moves in the opposite direction of hands of clock, then it can be said that the point is moving in ACW direction.

Analogy

lt is a similarity or comparability between like features of two things on which a comparison may be based. In these types of questions a series of numbers or alphabetical letters or combinations of both are given. The candidate is required to study the pattern and either to complete the given series with the suitable term or to find the wrong term in the series.
