Blood relation reasoning tricks | CSIR NET general aptitude classes

 

so now we are going to solve some

problems related to blood relationship

this is another kind of problem where

you don't need any formula or anything

that's we haven't discussed any formula

but simply simple iq and your own blood

relationship calculations might help you

to solve this one as well remember one

thing although we haven't discussed any

formula but there are something that

need to be told that need to be uh

discussed

and that idea simply is that this is you

this is your brother your cousin your

wife

all in the same generation

one generation above will be your father

your mother your uncle your aunt

everyone

two generation father grandfather

grandmother are there one generation

below you have your son daughter nephew

knees

all this okay then

granddaughter grandson and all so this

is a hierarchy if you remember this

hierarchy then you will be able to

answer most of these questions and

always make sure that not only this

hierarchy but also you need to put

yourself in terms of analyzing the blood

relationship that is asked in the

question

all right so in this case

how i related to sangeetha so let's

assume that sangeeta's daughter is my

daughter's mother

sangeeta's daughter

this is sangeeta's daughter

sangeetha's daughter is my daughter's

mother

okay this is me

and this is our daughter

and sangeetha's daughter is

the mother of my daughter so basically

sangeeta's daughter is my wife

isn't it so if shanghita's daughter is

my wife then how am i related to

shanghita

i am son in

law if i am male

if i am son in law if i am male

otherwise

otherwise if i am female

then of course i am

daughter

of shanghita otherwise there is no other

option so option d should be the correct

answer in this case got it quite easy

because basically sangita's daughter is

my wife

that's how the relationship comes in

now move to the second question

if a is a brother of b

so a and b belong to same lineage and a

is male so male with boxes female with

circle that's what we use b is the

sister of c

b is a sister

of c

c is the father of d

c is male father of

d

how d is related to a

so look at it a b c all belong to same

generation

same generation

so d is an a they are related one

generation above so basically

how d is related to a means d is nephew

d if male

nephew

a female knees

nephew or niece

isn't it

this is the idea

this can be the idea otherwise

but the thing is in this question if you

look at this question they haven't

clearly stated whether it's male or

female so male nephew otherwise knees

okay because a b and c following two

same generations there

so either you can say

nephew or nice

but

properly to be proper because in this

case we know that cd has a direct

relationship to c

okay

because a

is brother of b b sister of c

okay she's father of d so basically if

you are an easy as you can say that that

is the correct answer

now let's move to another problem here

and here

let's take a different color

deepak said to nitin

that boy playing with the football

is younger of the two brothers

of the daughter of my father's wife okay

that's too much information to process

the boys we're talking about a boy

male playing with football is younger of

the two brothers younger of the two

brothers

two brothers

okay

of the daughter so let's put the boy in

the center here

two brothers we are looking two brothers

we are looking here two brothers

younger that means one generation later

younger of the two brothers of the

daughter

brothers

these brothers

of the daughter

means this is the daughter

okay

of

daughter of

my father's wife

my father's wife my mother

and my mother's daughter

means this is where me should be placed

so basically my relationship with my

mother's daughter is my mother's

daughter is my sister

okay

how is the boy playing football related

to deepak me in this case is deeper

so deepak is male

how is the boy related to me

okay that boy playing the football is

younger of the two brothers so basically

not one generation below basically this

is another brother

so basically the boy is younger brother

younger brother

so boy is basically the younger brother

so in this case no younger or older only

says brother so we can see yeah b is the

brother of mine my brother of deepak

okay

so b is not in one generation below what

i said earlier basically it says that

the

the boy playing with the footballer is

younger of the two brothers so this is

younger than this two brother that

doesn't mean the b is in the next

generation of course so b is younger

brother than them and my mother's

daughter is my sister

and b is a brother of my sister so the b

is brother of me as well

got it

so don't get confused

this question will kill your time in cs

and exam that's why i told so only

answer the question which will save time

and not kill it pointing to a person

deepak said his only brother

see again the same type of question this

kind of quote unquote question gets more

difficult pointing towards the person

deepak said

his only brother is the father of

my daughter's father

my daughter this is me

my daughter in the next generation this

is me

my daughter's father means me

his only brother

so my only

brother so basically

we are introducing my only brother to

the person

okay so how is the person related to

deepak so if me means deepak here

so this is only brother means what

so

the the person the deepak is introducing

is basically uncle of

the uncle of whom the daughter means my

daughter uncle of my daughter

so the relationship is uncle remember

two things this is you and this is your

father

if they ask you how you are related to

your father the answer is son

how your father is related to you

father

remember that

this is very important from which

perspective we are finding the

relationship otherwise the total answer

will be wrong

so in this case

deepak said his only brother

is the father of my daughter's father

so basically how is the person related

to deepak

uncle

his only brother

this is this is the person deepak is

referring

his only brother

okay

is the father

of my daughter's father

this is my daughter's father so this is

this is me

means

my father

this is the person deepak introducing

deepak is stating here

deepak is stating here

this is deepak's father and this is the

person deepak is introducing so

basically deepak is one generation below

than this person

so deepak

and person how the person is related to

deepak uncle

how deepak is related to the person

nephew

got it

this is how it works

remember that always

because if you draw it correctly you

will answer it one go if you rethink it

two three times then this problem will

be really complicated in your mind so

the best deal for these problems blood

relation particularly is to solve at one

go

okay

otherwise

if you can solve it in one go then it

will be a big problem for you

fine

that's how we'll solve them

no such formula no such complications

simple issues and you can solve them
