MAT Exam 2022 Paper

Concept:Use family relationships to fix the tree and then match the known professions.Explanation:$\mathrm{U}$ is an Advocate and father of $\mathrm{P}$.$\mathrm{Q}$ is a Teacher and mother of $\mathrm{R}$.$\mathrm{R}$ is the brother of $\mathrm{P}$, so $\mathrm{U}$ and $\mathrm{Q}$ are the parents of both $\mathrm{P}$ and $\mathrm{R}$.$\mathrm{T}$ is the father of $\mathrm{U}$ and is a Doctor.$\mathrm{S}$ is the grandmother of $\mathrm{R}$ and is a Housewife, so $\mathrm{S}$ is the wife of $\mathrm{T}$.Thus, the two married couples are $\mathrm{T}-\mathrm{S}$ and $\mathrm{U}-\mathrm{Q}$.Known professions are: $\mathrm{U}$ Advocate, $\mathrm{Q}$ Teacher, $\mathrm{T}$ Doctor, and $\mathrm{S}$ Housewife.Therefore, the remaining two persons $\mathrm{P}$ and $\mathrm{R}$ must be the Student and the Engineer in some order.Since $\mathrm{U}$ is the father of both $\mathrm{P}$ and $\mathrm{R}$, and one of them is the Engineer, $\mathrm{U}$ is definitely the father of the Engineer.The other options cannot be concluded with certainty.Answer:Option A: $\mathrm{U}$ is father of the Engineer.
