### TYPES OF PROBLEMS:-

1) General Problems on Blood Relation.
(2) Blood Relation based on Family Tree.
(3) Coded Blood Relation.
Example 1 :- Q is the brother of C and C is the sister of Q. R and D are brother and sister. R is the son of A while A & C are wife and husband. How is Q related with D.

Solution :- For such type of question a family tree is made in which some symbols are used as below:

• Male
_ Female
| Next Generation
• Husband& Wife
= Brother and Sister
Adopting and using the above given symbols we can make a family tree and solve the given problem, let us see the family tree :

Step 1 – As per the question Q is the brother of C and C is the sister of Q. Hence, relation between C & Q has been presented as

where ‘–’ sign above C makes it clear that C is a female and ‘+’ sign above ‘Q’ makes it clear that Q is a male

Step 2 – For R and D. The presentation

Step 3 – A and C are having a husband and wife relationship and hence this has been presented

Step 4 – As it is already given that C is the sister of Q and A and C are wife and husband, this becomes clear that A is the male member of the family and this is the reason A has ‘+’ as its gender sign. Lastly, the vertical line gives father and son relationship and has been presented as

Now from this family tree it becomes clear that C is the mother of R and D and as Q is the brother of C, then Q will definitely be the maternal uncle of R & D. Hence, we can say that Q is the maternal uncle of D and this is
the required answer for our question.
Note : In solving family tree based relations make sure that your diagram is in correct representation.

Example 2 :- If P + Q means P is husband of Q,P/Q means P is the sister of Q,
PQ means P is the son of Q. How is D related to A in DB + C/A?

Solution :- C/A – >C is sister of A. B + C/A –> B is brother-in-law of A(Sister’s husband – broter-in-law) D*B + C/A – >D is nephew of (Sister’s husband’s son means sister’s son i.e., nephew)
So, D is nephew to A.

So, it is clearly shown that D is nephew to A
