II. Letters positions in forward alphabetical order:
III. Letters positions in backward or reverse alphabetical order:
Remember the word E J 0 T Y
IV. A, E, I, 0, U are vowels and remaining letters are consonants of English alphabet respectively:
V. A-M (1-13) letters are the first half of English alphabet.
VI. N-Z (14-26) letters are the second half of English alphabet.
Types of Questions
Type 1: Alphabetical Order of Words
Arranging words in alphabetical order implies 'to arrange them in the order as they appear in a dictionary'. First consider the first letter of each word. Arrange the words in the order in which these letters appear in the English alphabet.
Examples
1. Arrange the following words as per order in the dictionary.
A. Nose
B. Mouth
C. Eyes
D. Hair
(a) D, C, A, B (b) C, D, B, A
(c) A, B, D, C (d) D, C, B, A
Ans. (b)
Explanation: The given words begin with letters N, M, E, H respectively. Their order in English alphabet is E, H, M, N. Thus, the correct alphabetical order of these words is as follows:
\[Eyes\to Hair\to Mouth\to Nose\,i.e.\,C,D,B,A\]So, option (b) is correct.
2. Arrange the following words as given in dictionary.
1. Across 2. Admit 3. Advise 4. Alone more... 
CARDINAL DIRECTIONS
A direction between two main directions is called cardinal direction. Clearly there are four cardinal directions.
(i) N-E (North-East)
(ii) N-W (North-West)
(iii) S-E (South-East) and
(iv) S-W (South-West)
Note: Angle formed between two main directions is \[90{}^\circ \] and angle formed between a cardinal direction and main direction is \[45{}^\circ \]as shown in the above diagram.
ROTATION OF ANGLES
(i) For right direction movement (Clockwise)
(ii) For left direction movement (Anti-clockwise)
Left turn Anti-clockwise direction
Right turn Clockwise direction
The change in direction when a person or vehicle takes a right or a left turn
| Direction before taking the turn | Direction in which the person or vehicle will be moving after taking turn | |
| Right | Left | |

Coding Decoding
OBJECTIVES
· Students will develop the ability to understand the logic that cots a particular message to read the message.
INTRODUCTION
A code means arrangement of letters. Therefore, coding is a method of transforming any instruction from the given form to the required form.
CODING
A particular code patterh is used to express a word in English language to express it as a different word. The coded word itself does not make any sense unless we know the code, i.e. unless we know the pattern or code that has been followed.
DECODING
Decoding helps in tracing out the actual meaning of a coded letter/word sentence.
TYPES OF CODING
1. Letter Coding
2. Number Coding
3. Substitution Coding
4. Sentence Coding
5. Symbols Coding
Letter Coding
In these questions, code values are given to a word in terms of letters. A particular letter stands for another letter in letter coding.
Examples:
1. In a certain code language, TEACHER is written as VGCEJGT, then how will CHILDREN be written in that code language?
(a) ENAGITEV (b) PGTFNKJE
(c) EJKNFTGP (d) MGAETVIE
Ans. (c)
Explanation:
Similarly,
Hence, answer is (c).
Number Coding
In these questions, either numerical code values are assigned to a word or alphabetical code values are assigned to numbers.
2. If in a certain code ROPE is coded as 6821, CHAIR is coded as 73456 what will be code for CRAPE?
(a) 73456 (b) 76421
(c) 77246 (d) 77123
Ans. (b)
Explanation:
The alphabets are coded as follows:
