Embedded Figure
OBJECTIVES
· It will measure cognitive functioning and style of students.
· Students will be able to find shapes within the large more complex image.
INTRODUCTION
A figure is said to be embedded in figure (X), if figure (X) contains a part of that figure.
Types of Questions
Type I: Identify the Small Part hidden in given figure:
In such type of problem, figure (X), is given, followed by four parts, such that one of them is hidden in figure (X), students have to identify that part.
Example 1:
Identify which shape is hidden in the Figure (X).
(a) (b)
(c) (d)
Ans. (b)
Type II: Identify the Figure in Which Given Part is Hidden
In such problems, a figure X is given which is followed by four alternative of complex figures in such a way that figure (X) is hidden or embedded in one and only one of them. Student have to identify that particular figure in which the figure (X) is hidden.
Example 2:
(a) (b)
(c) (d)
Ans. (a)
Mirror/Water Image
OBJETIVES
· Students will learn how different objects are seen when they get reflected both in mirror and in Water.
INTODUCTION
The reflection of object into the mirror is called its mirror image. It is obtained by inverting an object laterally. If we combine the original figure and mirror image together they form symmetry.
MIRROR IMAGES
Mirror Images of Capital letters
· The capital letters which have the same mirror images are:
A, H, I, M, 0, T, U, V, W, X, Y
Mirror Images of Small letters
· The small letters which have the same mirror images are:
i, l, o, v, w, x
Mirror Images of Numbers
· 0 and 8 numbers have the same mirror images.
Mirror Image of Clock Time
For mirror image of clock time, the given time shall be subtracted from 12 00 or 11.60.
Example 1:
What will be the mirror image of clock time 3:40?
Explanation:
By using simple trick

Logical Reasoning
OBJECTIVES
· To identify relationships, similarities and difference between shapes and patterns.
· To recognize visual sequences and relationships between objects and remembering these.
INTRODUCTION
Visual reasoning is the process of manipulating one's mental image of an object to reach a certain conclusion.
Types of Questions
The chapter includes:
1. Grouping of figures.
2. Paper folding and cutting.
3. Merging and splitting of images.
4. Finding difference between two images.
5. Clock wise and anticlock wise rotation of objects.
6. Tessellation puzzle.
7. Completion of image.
8. Corresponding image.
9. Different sections of image.
10. Symmetry
11. Rule detection
Paper Folding and Cutting
In this type of questions, there are three or four figures given in one line. Each figure followed a pattern. Each figure consists of a dotted line along which it is to be folded and the arrow shows the side which it is to be folded.
After folding, the paper is cut or punched and then students have to visualize the correct figure that will be produced when the paper is unfolded.
Direction (Example 1): In the following example, a piece of paper is folded and cut and then unfolded. One of more...
Type I: How to arrange the numbers given to the
corresponding letter so that they form a meaningful word?
Arrange the letters in the different combinations given in options
to find a meaningful word.
Type II: Finding the word from
the options that can/cannot be formed from the given letters.
Students have to observe carefully all the letters given in the
question and find the combination of letters from the given options that
contains or does not contains letters.
Type III: How to form a meaningful
word and find the category of word?
Arrange the given jumbled letters in a meaningful word and
identify the category in which formed word lies.
Type IV: How to identify the
combination of letters that has same number of skipped letters between the
adjacent letters?
Write the alphabetical series in order, then observe carefully all
the options.
EXAMPLE
1. In the question, some letters are given which are
numbered 1, 2, 3, 4, 5 and 6 followed by four options containing combinations
of these numbers. Find the combination of numbers so that letters arranged
accordingly to form a meaningful word.
R F W E L O
1 2 3 4 5 6
(a) 2, 5, 6, 3, 1, 4 (b)
2, 5, 6. 3, 4, 1
(c) 1, 5, 6, 4,
3, 1 (d) 2, 5, 6, 1, 3, 4
Explanation (b):
First go through each option:
(a) 256314 = FLOWRE;
(b) 256341= FLOWER
(c) 256431 = FLOEWR;
(d) 256134= FLORWE
Meaningful word: FLOWER.'. Combination: 2, 5, 6, 3, 4, 1
2. Which word cannot be
made from the letters of the given word?
TEMPERAMENT
(a) METER (b)
PETER (c) TENT (d) TESTER
Explanations (d): S of the word TESTER
is not in the given word.
Type I:
How to find the missing term or next term in (number or letter) series to continue the given series?
How to decode the questions given in coded language?
In these type of questions, some particular words are assigned certain substituted names.
Then a question is asked that is to be answered in the substituted code language.
EXAMPLE
1. If' Wrist watch' is called 'Nail'; 'Nail' is called 'Phone' and 'Phone' is called 'Newspaper', then what do we wear on wrist?
(a) Wrist watch
(b) Nail
(c) Phone
(d) Newspaper
Explanation (b):
Wrist watch is worn on wrist and Wrist watch is called Nail.
2. If B means C, C means D and D means E, which alphabet is a vowel?
(a) B
(b) C
(c) D
(d) E
Explanation (c):
E is a vowel and D means E.
