**Introduction:** Analogies involve identifying relationships between pairs of words or
concepts. They help in understanding how different elements are similar in certain aspects, even
though they may differ in others. Analogies are often used in various tests and reasoning exercises
to assess the ability to recognize relationships and patterns.

**Basic Concepts:**

**Relationship:**The connection between two elements in a pair, which can be based on function, characteristics, or context.**Types of Analogies:**Common types include synonym analogies, antonym analogies, part-to-whole analogies, and cause-and-effect analogies.**Pattern Recognition:**The ability to identify similar relationships between different pairs or sets of elements.

**Key Formulas:**

**A : B = C : D:**

To solve analogy problems, find the relationship between A and B, and then apply the same relationship to C to find D.**Type of Relationship:**

Determine the type of relationship (e.g., synonym, antonym) between the first pair and find a similar relationship for the second pair.

A. Pup

B. Kitten

C. Cub

D. Calf

Think about the young form of a cat, similar to how a puppy is the young form of a
dog.

The relationship between Dog and Puppy is that of an animal to its young form.
Similarly, the young form of a Cat is a Kitten.

**Introduction:** Coding and decoding are methods used to encrypt and decrypt
information. Coding involves converting information into a coded form, while decoding is the
process of translating the coded information back to its original form. These techniques are
often used in cryptography and puzzles to test logical thinking and pattern recognition
skills.

**Basic Concepts:**

**Coding:**The process of converting a message into a different format using a specific code or algorithm.**Decoding:**The process of converting the coded message back to its original form.**Common Techniques:**Substitution ciphers, transposition ciphers, and code books.

**Key Formulas:**

**Substitution Cipher:**

Each letter in the plaintext is replaced with another letter. For example, in a Caesar cipher with a shift of 3, 'A' becomes 'D', 'B' becomes 'E', and so on.**Transposition Cipher:**

The positions of the letters are shifted according to a specific system, such as a grid or columnar transposition.

A. 3145

B. 3155

C. 3125

D. 3156

Convert each letter to its corresponding number and then combine them.

C = 3, O = 15, D = 4, E = 5. Combining these numbers gives 3155.

A. The secret message

B. The secret code

C. The hidden
message

D. The hidden code

Shift each letter back by 5 positions in the alphabet.

Shifting each letter of "Ymnx xjhwjy jshwdu" back by 5 positions gives "The
secret message."

A. SUOOL

B. SVOOL

C. HELLZ

D. ZOOVK

Reverse the position of each letter in the alphabet.

Using the substitution cipher where A=Z, B=Y, C=X, etc., H becomes S, E
becomes V, and so on, making "HELLO" encode to "SVOOL."

A. FZQCDM

B. EZQCDN

C. GZQFDO

D. HXSEFO

Each letter is shifted backward by one position in the alphabet.

F->E, L->K, O->N, W->V, E->D, R->Q. Similarly, for "GARDEN": G->F, A->Z,
R->Q, D->C, E->D, N->M.
Therefore, "GARDEN" is coded as "FZQCDM."

A. NWPEJ

B. MWPEI

C. NVODH

D. KWNEJ

The position of each letter is shifted two steps forward.

M->O, E->G, A->C, L->N; similarly, L->N, U->W, N->P, C->E, H->J. The code
for "LUNCH" is "NWPEJ."

**Introduction:** Number Series is a sequence of numbers following a specific pattern.
Identifying the pattern helps to predict the next number in the series or find missing numbers.

**Basic Concepts:**
