Suggested Method for questions like
• In questions of this type, what is required is to establish the
relationships among the members of a whole family and not
between two persons as in E.g. 1. such question can be easily
solved by drawing a family tree dragram.
• Drawing a family tree.
• (a) Vertical or diagonal lines should be used to represent parent-
• (b) A double horizontal line ( like ) should be used to represent
• (c) a dashed line should be used to represent brother or sister
• (d) Put a + sign before someone who is a male and a - sign before
some one who is a female.
• (e) Whenever something is not known put a? mark or some symbol
(x, y, z, @, $ ......)
• For example, consider the following diagram
• The above diagram tells as that
• (i) B and D are a couple, D is the husband
• while B is the wife.
• (ii) B has a brother A.
• (iii) The couple, B and D have three children
F, E and G. (Note : Apart from vertical or diagonal
lines, son or daughter are also easily established if
two persons are connected be dashed lines.
Also Note that
• E is the brother of F even though there is
no dashed line, but they have the same root.)
• Of three children E is male, G is female, but
the sex of F is not known.
• (iv) C and G are a couple, C is the husband and
G is the wife.
• They have one child H whose sex is not known
Points to be Noted :
(i) It is advisable to being with a sentence that gives
information about parent-child relationship.
• Grandfather-grandmother relationships and
brother-sister relatioships should be touched
(ii) Try your best that you do not draw a new
diagram for every new information that you read.
• Instead, try to 'add' to the existing diagram on
reading a new information.
• In a family, there are six members A, B,C, D, E, and F. A and B are a
married couple, A being the male member. D is the only son of C,
who is the brother of A. E is the sister of D. B is the daughter-in-law
of F, whose husband has died.
1. How is F related to A?
• 1) Mother (2) Sister-in-law (3) Sister (4) Mother-in-law
(5) None of these
2. How is E related to C?
• (1) Sister (2) Daughter (3) Cousin (4) Mother (5) None of these
3. Who is C to B ?
• (1) Brother (2) Brother-in-law (3) Son-n-law (4) Nephew (5) None of
In a family, there are six members A, B,C, D, E, and F.
A and B are a married couple, A being the male member.
D is the only son of C, who is the brother of A.
E is the sister of D.
B is the daughter-in-law of F, whose husband has died.
• We start with the 3rd sentence,
since it given a parent-child
• The diagram is:
• Now, we should look for a
sentence that given information
about A or C or D, The second
sentence is appropriate.
Incorporating it into the diagram,
• Now, we incorporate the fourth
• Finally, we incorporate the last
sentence. Note that F must be a
female because her husband has
died. [One who has/had a
husband must be a female.]
