Answer – T is mother-in-law of P and P is wife of R. So, R is P’s husband and T is mother of R. So one couple is RP. Since S is father of U , so S is the husband of T. So the other couple is ST

Since Q is sister of U,so R,U and Q are children of S and T. Since there are 3 males in all, so U is also a male.

Now Q reads NT, U reads HT, T reads IE. Since S does not read TOI or TT, so S reads BH. Since R does not read TT so R reads TOI. Clearly P reads TT.
