Interview Question for Technical or Non Technical Students
Blood relations
Introduction to Blood relations
Blood relation is one of the most important topics of logical reasoning and found its
importance in almost every entrance exam. This topic tests the analytical skills of the
students and their solution approach. The questions asked in this chapter depend upon
‘Relations’. You should have a sound knowledge of the blood relation in order to solve
the questions.
To remember easily, the relation may be divided into two forms:
Relation of the paternal side
Father’s father => Grandfather
Father’s mother => Grandmother
Father’s brother => Uncle
Father’s sister => Aunt
Children of uncle => Cousin
Wife of uncle => Aunt
Children of aunt => Cousin
Husband of aunt => Uncle
-----------------------------------------------------------------------------------------------------------------------------
Relation of the maternal side
Mother’s father => Maternal Grandfather
Mother’s mother => Maternal Grandmother
Mother’s brother => Maternal Uncle
Mother’s sister => Aunt
Children of maternal uncle => Cousin
Wife of maternaluncle => Maternal Aunt
Children of the maternal aunt => Cousin
Husband of the maternal aunt => Maternal Uncle
-----------------------------------------------------------------------------------------------------------------------------
Others
Son’s wife => Daughter-in-law
Daughter’s husband => Son-in-law
Husband’s (or) wife’s father => Father-in-law
Husband’s (or) wife’s mother => Mother-in-law
Husband’s (or) wife’s brother => Brother-in-law
Husband’s (or) wife’s sister => Sister-in-law
Sister’s husband => Brother-in-law
Brother’s (or) sister’s son => Nephew
Brother’s (or) sister’s daughter => Niece
-----------------------------------------------------------------------------------------------------------------------------
Relations from one generation to other
Generation1:Grandfather, Grandmother, Maternal grandfather, Maternal grandmother
Generation 2: Mother, Father, Uncle, Aunt, Maternal uncle, Maternal aunt
Generation 3: Self, Sister, Sister-in-law, Brother, Brother-in-law
Generation 4: Son, Daughter, Nephew, Niece
Symbols
1. ‘+’ for male 2. ‘-’ for female 3. ‘ ’ for couples
-----------------------------------------------------------------------------------------------------------------------------
Type 1: Statement based relationship questions
Problem 1:
Pointing to a lady on the stage, Sonali said, “She is the sister of the son of the wife of
my husband.” How is the lady related to Sonali?
Solution:
My husband = Sonali’s husband
Wife of my husband = is me = Sonali
Son of the wife of my husband = My Son
Sister of the Son of the wife of my Husband = My Son’s Sister = My daughter
So, the lady on the stage is Sonali’s daughter.
Problem 2:
Eeshas father was 34 years of age when she was born. Her younger brother,
Shashank, now that he is 13, is very proud of the fact that he is as tall as her, even
though he is three years younger than her. Eeshas mother, who is shorter than Eesha,
was only 29 when Shashank was born. What is the sum of the ages of Eeshas parents
now? (asked in TCS)
a) 92
b) 76
c) 66
d) 89
Answer: a) 92
Solution: Let Eesha's present age be x.
Eesha's father's present age = x + 34
Shashank's age = 13
Eesha's present age = 13 + 3 = 16
Eesha's mother's present age = 29 + 13 = 42
Sum of the ages of Eeshas parents now = 42 + 16 + 34 = 92
Problem 3:
Pointing to a lady a man said, “Her husband is the only son of my mother”. How is the
lady related to the man?
Solution:
My mother’s only son = is me ( man)
Her husband = is me
So, the lady is Man’s wife.
Problem 4:
Pointing to Alex, Lita says, “I am the daughter of the only son of his grandfather.” How
Lita is related to Alex? (Asked in Sapient)
a) Niece
b) Daughter
c) Sister
d) Cannot be determined
Answer: C) Sister
Solution:
Lita is the daughter of the only son of Alex’s grandfather. Hence, it’s clear that Lita is
the sister of Alex.
Problem 5:
Pointing to a man Manisha said, “He is the youngest son of my father-in-law’s only
son”. How is Manisha related to this youngest son’s father?
a) Sister
b) Sister-in-law
c) Wife
d) Mother
Solution:
Manisha’s father in law’s only son = Manisha’s husband
The youngest son of my father-in-law’s only son is my husband’s son = My son =
Manisha’s son
So, Manisha is the wife of the youngest son’s father
-----------------------------------------------------------------------------------------------------------------------------
Type 2: Puzzle type questions with a family relationship component
Problem 1:
A family consists of a husband and wife, their three sons and two daughters, three
wives of three sons. How many females are in this family? (Wipro hiring 2018)
Solution:
Husband wife (female)
Three sons = S1 S2 S3 and two daughter = D1 D2
Son’s wives = W1 W2 W3
So, the total number of females = wife + D1 + D2 + W1 + W2 + W3 = 6 females.
-----------------------------------------------------------------------------------------------------------------------------
Directions for problem 2 to 6:
If a + b means, a is the daughter of b,
a - b means, a is the husband of b,
a b means, a is the brother of b. ×
Problem 2:
What does the relation p q - r show? ×
(a) p is the son-in-law of r
(b) p is the brother of r
(c) r is the wife of p
(d) None of these
Solution:
p q means p is the brother of q ×
q - r means, q is the husband of r i.e.
p is the brother-in-law of r or r is the sister-in-law of p.
So the answer to this question is an option (d).
Problem 3:
If h+i j+k l+m n, then what is the present generation of h. Assume that the oldest × × ×
generation of this group is 1st generation.
(a) 2nd (b) 3rd
(c) 1st (d) None of these
Solution:
Here symbol ‘+’ is for a generation change.
m n = m is the brother of n ×
l+m = l is the daughter of m (1st generation)
k l = k is the brother of l ×
j+k = j is the daughter of k (2nd generation)
i j = i is the brother of j ×
h+i = h is the daughter of i (3rd generation)
Hence, present generation of ‘h’ = 3rd generation i.e. option (c)
Problem 4:
Which of the following options does not hold?
(a) a+b c ×
(b) a-b c ×
(c) a+b+c
(d) a+b-c
Solution:
(a) a+b c, here ‘b’ is the brother of ‘c’ i.e ‘b’ is a male and ‘a’ is the daughter of ‘b’. ×
This option is correct.
(b) a-b c, here ‘b’ is the brother of ‘c’ i.e ‘b’ is a male and ‘a’ is the husband of ‘b’ ×
This option can not hold. ‘a’ can’t be the husband of ‘b’, because ‘b’ comes out a
male.
Problem 5:
From the statement a b c d, which of the following statements is not necessarily × × ×
true?
(a) ‘b’ is the brother of ‘a’
(b) ‘c’ is the brother of ‘a’
(c) ‘d’ is the brother of ‘c’
(d) a,b,c are male
Solution:
a b c d, here ‘c’ is the brother of ‘d’, ‘b’ is the brother of ‘c’ and ‘a’ is the brother of ‘b’ × × ×
So, here a,b,c are males.
Option (c) ‘d’ is the brother of ‘c’ is not necessarily true because we don’t know
whether ‘d’ is male or not.
Problem 6:
From the statement p-q+r s, how is ‘q’ related to ‘s’? ×
(a) Niece
(b) Sister
(c) Daughter
(d) Brother
Solution:
r s = ‘r’ is the brother of ‘s’ ( ‘r’ is male) ×
q+r = ‘q’ is the daughter of ‘r’(‘q’ is a female)
p-q = ‘p’ is the husband of ‘q’
So from the above conclusion, ‘q’ is the niece of ‘s’ i.e. option (a) is the correct answer.
-----------------------------------------------------------------------------------------------------------------------------
Directions for questions 7 to 8.
a*b means ‘a’ is the brother of ‘b’
a@b means ‘a’ is the daughter of ‘b’
a$b means ‘a’ is the sister of ‘b’
Problem 7:
Which of the following show the relationship ‘p’ is the paternal uncle of ‘c’?
(a) n $ o @ p
(b) n @ o $ p
(c) n @ o * p
(d) None of these
Solution:
(a) n $ o @ p
o @ p = ‘o’ is the daughter of ‘p’ and n $ o = ‘n’ is the sister of ‘o’
So, here ‘p’ is either the father or the mother of ‘n’.
(b) n @ o $ p
o $ p = ‘o’ is the sister of ‘p’ and n @ o = ‘n’ is the daughter of ‘o’
So, ‘p’ is either uncle or aunt of ‘n’ because the gender of p can not be
determined.
Hence, the answer will be an option (d).
Problem 8:
a$b$c@d@e*f*g, then how many males and females are there respectively?
(a) 4,3
(b) 3,4
(c) 5,2
(d) Can’t be determined
Solution:
f*g = ‘f’ is the brother of ‘g’ ( i.e. ‘f’ is a male)
e*f = ‘e’ is the brother of ‘f’ ( i.e. ‘e’ is a male)
d@e = ‘d’ is the daughter of ‘e’ (i.e. ‘d’ is a female)
c@d = ‘c’ is the daughter of ‘d’ (i.e. ‘c’ is a female)
b$c = ‘b’ is the sister of ‘c’ (i.e. ‘b’ is a female)
a$b = ‘a’ is the sister of ‘b’ (i.e. ‘a’ is a female)
Here we can not find the gender of ‘g’.
Here 4 women and 2 men but we can't find the gender of one person.
So, the answer is can’t be determined, option(d)

Calendar Problems
Introduction to Calendar problems
The calendar is a small chapter but an important chapter of the reasoning part.
Questions in calendars come from time to time for you in your exams.
A calendar is a series of pages that contains days, weeks, and months of a particular
year and gives information.
Normal year: Any year which contains 365 days is called a normal year.
Leap year: Any year which contains 366 days is called a leap year.
Odd days: those number of available days from which we can’t complete a week are
called odd days.
A normal year has 365 days. In which there are 52 complete weeks and the last day
would be an odd day. It would shift the calendar ahead or behind by a certain day.
Suppose in a normal year you start 1st January of the year on Monday, then 30th Dec of
that year would be a Sunday and 31st Dec being a Monday and hence, the 1st Jan of the
next year will skip the calendar forward by one day.
A leap year has 366 days. If 1st Jan starts with Monday of leap year then 29th Dec would
be the last Sunday of that year. 30th Dec will again Monday and 31th Dec will be
Tuesday. Hence, 1st Jan of the next year will skip by 2 days.

NOTE:
1. The number of odd days in the first 100 consecutive years is 5.
2. The number of odd days in the first 200 consecutive years is 3.
3. The number of odd days in the first 300 consecutive years is 1.
4. The number of odd days in the first 400 consecutive years is 0.
---------------------------------------------------------------------------------------------------------------------------
Example 1:
11 August 2019 is a Sunday, what day was on 11 August 1983?
Solution:
To find the day on 11 August 1983, you have to count the number of odd days.
From 1983 to 2019 there are 36 years. This means 36 odd days and now count how
many leap years or 29th Feb will appear.
So, 29th Feb would appear in 1984,1988,1992,1996,2000,2004,2008,2012,2016. So, 9
leap years means 9 further odd days.
Hence, the total number of odd days = 36+9=45 days
45 days have 6 complete weeks and 3 odd days left out.
Going behind 3 odd days from Sunday. Hence, 11 August 1983 would be a Thursday.
