NA
Reject option (a) because the equation does not tell about sex of R.
Reject (b) and (c) also on the same basis.
In equation 2) M is the grandson of K. This implies that with the help of the given information in the direction, it is possible to form an equation which can show that R is the grandson of K.
Hence, reject (d) also.
We cannot find the sex of M in any option.
Hence, M is either grandfather or grandmother of F.
According to the question,
Here, S and P are first cousins.
One's grandfather's only son ? one's father and the son of one's father ? One's brother or oneself.
Hence, the mother of the boy is Meena's mother
Clearly, B and C are siblings. While A and D are parents.
Now, A is the mother. Hence, D must be the father.
as we don't know the gender of L.
only option a says that S is mother of T.
Brother
H as be the father of K than definitely N should be the mother.
Son-in -law
