DIRECTION SENSE TEST

1. The shortcut for solving problems related to direction sense is drawing schematic or block diagrams of the given data.
2. The four directions are North, South, East and West..
3. North-East (NE), South-West (SW). North-West (NW) and South-East (SE) are the four main cardinal directions.
4. If a person A is standing at the time of sunrise, his shadow will point towards the West.
5. During sunset, the shadow of an object is always pointing towards the East.
6. If a man stands facing the North, at the time of sunrise his shadow will be towards his left and at the time of sunset it will be towards his right.
7. There will be no shadow at 12 Noon, as the rays of the Sun are vertically downwards.
8. The angle between any two main (or cardinal) directions is 90° but the angle between one main and one cardinal direction is 45°.
   
   

ALPHANUMERIC SEQUENCE PUZZLE

1. The combination of alphabetic and numeric characters is called Alphanumeric. In some cases, it may include upper-case and lower-case letters, punctuation marks, and symbols (such as @, &, and *).
2. Few key words that are used in such questions are "following, followed by, preceding, and preceded by".
3. Let us take two successive letters A and B. Here, A is preceding B and B is preceded by A. Also, B is following A and A is followed by B.
4. Now, take three successive letters A, B and C. Here A and B are preceding C, where B is immediately preceding C but A is not immediately preceding C. Similarly, B and C are following A, where B is immediately following A but C is not immediately following A.
   
   

MATHEMATICAL OPERATIONS

The four fundamental mathematical operations are:
i) Addition
ii) Subtraction
iii) Multiplication
iv) Division
Such questions can be solved by substituting the real signs in the given expression, and then solving the expression following the BODMAS rule.

ORDER OF OPERATIONS – BODMAS

B - Brackets (do all calculations of the brackets first)
O - Orders, square roots, powers
D - Division
M - Multiplication
A - Addition
S - Subtraction

RANKING:

The steps that we follow:
Read each line of the statement carefully.
Position can be either side of the row, while rank is from the top to the bottom of a row.
Rank of a person from lower = total persons in a row - rank of that person from upper + 1
Rank of a person from the right = total persons in a row - rank of that person from left + 1
Rank of a person from upper = total persons in row - rank of that person from lower + 1
Rank of a person from the left = total persons in row - rank of that person from right + 1
Total persons in a row = rank of a person from upper / left + rank of a person from lower / right – 1

NEW WORD FORMATION :

Write down the given word on a rough paper and number the individual letters according to the alphabetical series.
For easy identification, round off the given words as given in the question.
Then take the word circles and form sequences one after another letter and count the number of meaningful words formed.
Some questions are about finding more than one meaningful word from a given keyword. Here, you can make two words with the given keyword, and mark the option which has more than one word as answer.

Example :

How many meaningful English words can be formed with letters TPA using each letter only once?
a) Three b) Two c) One d) Five
Answer: a) Three

Explanation :
Three words can be formed with letters TPA.

i.e., PAT, TAP and APT
