Direction Test

                                                                                        Direction Test   Learning Objectives
  • Concept of Direction
  • Concept of Turn
  • Concept of Minimum Distance
  Concept of Direction In our day to day life we make our concept of direction after seeing the position of the sun. In fact, this is truth that sun rises in the East and goes down in the West. Thus, when we stand facing sunrise then our front is called East while our back is called West. At this position, our left hand is in the northward and the right hand is in the southward. Let us see the following direction map that will make your concept more clear.   Direction Map:   Note: On paper North is always on the top while South is always at the bottom.   Concept of Turn more...

Coding Decoding

                                                                                           Coding-Decoding   Learning Objectives
  • What is Coding-Decoding
  • How to Decode
  What is coding-Decoding? Let us start it with an interesting story. Suppose you and your father like ice-cream very much. But your mother does not want you two to have it because you both catch cold very easily. Then you and your father make a secret plan to use the word 'Chocolate' for ice-cream. Now, whenever you feel like eating ice-cream you say to your father that you want to eat chocolates. Mother hears it and thinks that you are really demanding chocolates. Therefore, she gives you permission to go out with father and enjoy chocolates. Then you and your father go out, eat ice-cream and comeback.   What do you think happens here? Here, you coded the word Ice-cream' with another word 'Chocolate'. Only you more...

Letter Series

                                                                                 Letter Series   Learning Objectives
  • What is a Letter Series
  • Properties of Letter Series
  • Types of Problems
  What is a Letter Series? A letter series is a sequence of many elements made of letters of English alphabet only. Such sequence is formed by putting the letters one after another from left to right.   Example: (i) A BCD (ii)  DCB A (iii) AL BL CB DE   Note: An element of a series is a single member (identity) of that particular series. For example, in a letter series 'A B C D', each A, B, C and D is a single element. more...

Number Seriese

                                                                                     Number Series   Learning Objectives
  • What is a Number Series
  • Types of Problems
  What is a Number Series? A number series is a sequence of numbers which follow a particular rule. Each element of a series is called a 'term'. In this chapter, we will analyse the pattern of different kind of number series that a particular series follow and find the missing term to continue the pattern.   Example Find the missing term in the given series. 2, 8, 32, 128, __. (a) 512                          (b) 510 (c) 516                          (d) 520 (e) None of these   Answer (a) Explanation: Option (a) is correct. The relationship between the terms or the pattern that the given series follows is as below. Therefore, the next term or missing term of the given series will be   Find more...

Time and Clock

                                                                                    Time and Clock   Learning Objectives
  • Time and Clock
  Time and clock Clock is a device which is used to measure and display the time. The face or dial of a clock is divided into 60 equal parts called minute space and it is numbered from 1 to 12, in such a way that each subsequent number is equidistant (5 minutes spaces apart) from the preceding number. A clock has two hands, the smaller one is the hour hand/ while larger one is called the minute hand. When hour hand travels five minutes spaces, the minute hand travels 60 minutes spaces. Therefore, in 60 minutes the minute hand gains 55 minute on the hour hand.     Properties of clock

Non-Verbal

                                                                                                  Non-Verbal   Learning Objectives
  • What is Non-Verbal Reasoning
  • Types of Problems
  What is Non-verbal Reasoning Non-Verbal reasoning is a figure based reasoning. It has no language at all. To solve non-verbal problems one has to find out the pattern of pictorial presentation in the given figure. To get a more clear concept about non-verbal reasoning. Let us see the types of problems coming before you.   Types of Problems Problems Based on Mirror Image In a mirror image, left part of an object becomes right part and right part becomes left part. Remember the rule given below, Left Hand Side (LH.S.) \[\overset{{}}{leftrightarrows}\] Right hand Side (R.H.S.)   Example 1

Number System

                                                                                           Number System   Learning Objective
  • Number System
  • HCF
  • LCM
  Number System A system of naming or representing numbers.   Number A number is a mathematical object which is used to count, label and measure,   Example 1, 5, 19, 325   Main Type Natural numbers/whole-numbers, integers, rational numbers, irrational numbers, real numbers.   Natural Numbers Counting numbers 1, 2, 3, 4, 5, 6... are called natural numbers. These numbers are also referred to as the positive integers. Properties
  • The set of natural numbers, commonly denoted by N.
  • 1 is the smallest natural number.
    • No largest natural number can be found because the set of natural numbers is infinite,
  • The successor of a natural number is 1 more than the number.
  • The predecessor of a natural number is 1 less than the number.

    Algebra

                                                                                Algebra   Learning Objectives
    • Algebra
    • Ratio
    • Proportion
      Algebra Algebra is generalized arithmetic in which unknown or unspecified numbers are represented by using letters known as literals.   Constant and variable: A symbol having a fixed numerical value is called a constant and a symbol which takes on various numerical values is known as variables., Example: \[8,-25,\text{ }6\frac{6}{11},\,3\frac{1}{2}\] are examples of constants whereas a, b, c, u, u x and y are examples of variables. Algebraic expression: An algebraic expression composed of arithmetic numbers, letters and signs of operation.   Example: \[5x+8,\text{ }9y+3x\] and 8z are examples of algebraic expressions. Terms of an expression: Various parts of an algebraic expression separated by the signs plus (+) or minus (-) are known as the terms of the expression. Example: The algebraic expression \[6x+8y+9\] have three terms, 6x, 8y and 9. more...
