Common explanation for question no. 1 to 3:
Reference:
Twelve persons consist of a family spanning over three generations. Also,
there are three married couples and all the female members of the family
are married. For every person in the family either both or none of his/her
parents are alive.
Inference:
With the above hints we can easily figure out that there are only three
female members in the family and we will keep the rest of this information
in mind while solving the puzzle.
Reference:
Both the daughters of Aby have 2 sons and 2 brothers.
Kat is mother of Jay and Cal is father of Kat.
Inference:
As we know that all the females of the family are married. Then,
Reference:
Sia and Rai are cousins of Jay.
Map and Eva both are uncles of Sia and Han.
Inference:
After using the above hints, we have:
Reference:
Ira is not unmarried person.
Dep married to Tur, who is aunt of Han.
Inference:
After using the given hints, the above blood chart can be redrawn as:
1.
Following the final solution we can say that Cal is the father in law of Ira.
Hence, option D is correct.
2.
Following the final solution we can say that Sia is the son of Tur.
Hence, option E is correct.
3.
Following the final solution we can say that Eva has three siblings.
Hence, option D is correct.
4.
Brief: ‘‘R@P$Q/S*T’’
R is the son of P. Q is the brother of P. Q is the father of S. T is the sister of
S.
Clearly, gender of P and S cannot be determined, thus we can't say whether
S is the brother of T or the sister of T. Therefore this conclusion cannot be
drawn from the given expression.
Hence, option C is correct.
5.
Brief: 'M#S$J@W*P'
M is the husband of S. J is the brother of S. J is the son of W. P is the sister
of W.
Clearly, gender of W cannot be determined, thus we can't say whether W is
the father-in-law or the mother-in-law of M. Therefore this conclusion
cannot be drawn from the given expression.
W has two children can clearly be derived from the above family tree.
P is also explicitly seen as the aunt of J.
Hence, option D is correct.
6.
Option A – Brief: 'K@G$T#Y*U'
K is the son of G. T is the brother of G. T is the husband of Y. U is the sister
of Y.
Here we don't know the gender of G, thus we can't say whether G is
brother-in-law or sister-in-law of Y. Thus option A gets eliminated.
Option B – Brief: 'G/K@T*U$Y'
G is the father of K. K is the son of T. U is the sister of T. Y is the brother of
U.
Clearly, in the above image, G can be derived as brother-in-law of Y.
Thus option B is the correct choice.
Hence, option B is correct.
Common explanation for question no. 7 to 8:
Reference:
Pointing to a photograph Ankur says, ‘He is the only brother of the only
daughter of my sister's maternal grandmother.’
Inference:
Using the above information, we have:
Reference:
Pointing to another photograph Suraj says, ‘He is the only brother of the
only daughter of my sister's maternal grandmother’.
Inference:
Using the above information, we have:
In both of the figures we can see that both Ankur and Suraj are pointing
towards their maternal uncle.
Reference:
Among the two photographs, one was either of Suraj or Ankur, and the
photograph, towards which Ankur was pointing, was not of Suraj.
Inference:
With the above hints it is clear that one of the given photograph was either
of Ankur or Suraj, and it is given that Ankur was not pointing towards
Suraj’s photograph also none of Ankur or Suraj can point towards their own
photograph so no one can be his own maternal uncle. This, means Suraj
was pointing towards Ankur’s photograph.
So, we can say that Ankur was the maternal uncle of Suraj.
Blood tree after combining statements of both Ankur and Suraj:
7.
Following the final solution we can say that Ankur is the maternal uncle of
Suraj.
Hence, option C is correct.
8.
Following the final solution we can say that Ankur's is the mother of Suraj.
Hence, option A is correct.

Reference:
Tiya is grandmother of Drona.
Gaur has two children Ali and Drona.
Minu has no son.
Inference:
After using the given hints, above blood chart can be redrawn as:
9.
Following the final solution we can say that there are 2 male members in
the family.
Hence, option B is correct.
10.
Following the final solution we can say that Drona is the granddaughter of
Joya.
Hence, option D is correct.
