MAT Exam 2022 Paper

Concept:This is a family-relations and generation puzzle. Arrange the given members in a family tree and then check each statement with the profession clues.Explanation:$K$ is the husband of $X$, and $X$ is the mother of $P$.$P$ is the brother of $T$; both have the sister $O$.So $P$, $T$ and $O$ are children of $K$ and $X$.After arranging the family tree, $S$, $P$, $T$ and $O$ are in the 2nd generation, so statement (b) is true.Given that $Q$ and $K$ are associated with engineer and accountant, and $K$ is not an accountant, $K$ is the engineer and $Q$ is the accountant.Thus, the husband of $X$ is an engineer, so statement (a) is true.The accountant is $Q$, and $L$ is his wife.The family tree shows that $Q$ and $L$ belong to the 3rd generation, not the 4th generation.Hence, statement (d) is not true.The female members are $X$, $O$, $S$, $L$ and $N$, so there are 5 female members, making statement (c) true.Answer:Option D — The accountant and his wife belong to the 4th generation.
