We cannot find the sex of M in any option.
Hence, M is either grandfather or grandmother of F.
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.
NA
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
as M is wife of G
None of these
