In this section/ problems are based on blood relations. The process of solving these problems (puzzles) depends upon the deep knowledge of blood relations. The common relations are: Father, Mother, Grandparents/ Wife, Husband/Son, Daughter, Grandchild, Sister, Brother etc.
Remarks:
1. Relatives on the mother's side are called 'maternal'. For example, mother's brother is called maternal uncle.
2. Relatives on the father's side are called 'paternal'. For example, father's brother is called paternal uncle.
3. Assume a relation as paternal relation, unless stated otherwise.
EXAMPLE
1. A woman going with a boy is asked by another woman about the relationship between them.
The woman replied, "My maternal uncle and the uncle of his maternal uncle is the same."
How is the lady related with that boy?
(a) Grandmother and Grandson
(b) Mother and Son
(c) Aunt and Nephew
(d) Sister and brother
Explanations: (c)
The brother of woman's mother is the same as brother of the father of boy's maternal uncle. Also, the woman's mother's brother is the boy's maternal uncle's father, Thus, the woman's mother's brother's son is boy's maternal uncle, i.e., woman's mother's brother's daughter is boy's mother.
So, the woman and boy's mother are cousins. Thus, the woman is boy's aunt. Hence, the answer is (c).
2. A and B are brothers. C and D are sisters. A's son is D's brother. How is B related to C?
(a) Father (b) Brother
(c) Uncle (d) Grandfather
Explanation: (c)
Clearly, A's son is C's brother. This means C is the daughter of A. So, B is the uncle of C. Hence, the answer is (c).
3. If 'P + Q' means 'P is the father of Q', means 'P is the brother of Q' and 'P - Q' means 'P is the mother of Q', then which of the following is definitely true about C ? A+B?
(a) B is the son of A (b) B is the father of A

In puzzle test, some information is provided in the form of a puzzle and hence one or more questions are put up on the basis of it.
To answer these questions, a student is required to simplify the puzzle in his/her own language.
The puzzle may be of any field such as:
1. Seating/placing arrangement.
2. Comparison of heights, weights, sizes, etc.
3. Family basis.
4. Sequential order of things.
EXAMPLE
1. Among four friends, Mohit is thrice the age of Kartik. Tarun is half times younger to Kartik.
Anuj is six years older to Kartik, but six years younger to Mohit. Who is the eldest?
(a) Tarun (b) Kartik
(c) Anuj (d) Mohit
Explanation: (d)
Mohit = 3 (Kartik)
Tarun = (Kartik)
Anuj = Kartik + 6 = Mohit -6
Therefore, Mohit > Anuj > Kartik > Tarun
So, Mohit is the eldest.
2. Six friends A, B, C, D, E and F are seated on a round table facing the centre.
F is between A and D. C is between E and B. E is not just between D and C. D is second to the left of C.
Who is sitting between A and C?
(a) B (b) D
(c) E (d) C
Explanation: (c)
All face towards the centre
We observe that E is sitting between A and C.
When an input of some numbers is given to a number generating machine, it gives sets of numbers in a specific pattern as an output.
Infect an input may be of letters/words or numbers or combination of both.
A student is required to analyses the data (input and output) and identify the pattern to answer the questions.
Let us write some commonly used patterns:
1. Arrangement of the given numbers in ascending/descending order.
2. Arrangement of the given numbers stepwise in the order: greatest, smallest, second greatest, second smallest, and so on.
3. Arrangement of given words in alphabetical and reverse alphabetical order.
4. Arrangement of a particular set of words in the reverse order, stepwise.
EXAMPLE
1. Direction (I-II): Study the following information to answer the questions given below:
A number arrangement machine when given an input of numbers, rearranges them by following a particular rule in each step. The following is an illustration of an input and steps of rearrangement.
