M x N % S +T means, mother of the wife of the son. M is N’s mother.
N % S means N is the wife of S.
And S is the father of T.
Therefore N is the mother of T and M is the mother of M. (Mother of the wife and grandmother of the son).

Maternal Grandmother means grandmother from mother side. Not of father side.

I don't understand it. Please, anyone, explain

I think M*N*S%T also possible.

Because M is the mother of N. and again N is the mother of S.

So that means S is the daughter of N and M already is mom's mom. So she(M) is the grandmother of S.

Now S is the wife of T. So we all know if the M is the grandmother of S. i.e, also grandmother for T as well. So we can say T is the son-in-law of M&N
