Question

Which of the following combinations of subject and place of stay is not correct?

• A. English - Hostel
• B. Mathematics - PG
• C. Philosophy - Home
• D. Physics - Hostel
• E. None of these

Answer 1

Answer: (A)

English - Hostel

	Place of Stay	Subject
$P$	PG	English
$Q$	Home	Statistics/ History
$R$	Home	Philosphy
$S$	Hostel	Physics
$T$	PG	Maths
$U$	Hostel	Statistics/ History

From $5^{th}$ and $6^{th}$ statement, $T$ stays as PG and studies mathematics. Also, $S$ stays in hostel and studies physics.
$R$ studies philosophy and doesn't stay as PG. He can't stay in hostel since $U$ and $S$ already do so two spots are filled. Thus, $R$ stays at his home.
$U$ stays in hostel and $Q$ stays at home from $6^{th}$ statement.

Thus these both can only be doing Statistics/History because $P$ and $T$ stay as PG. And subjects of $R$ and $S$ is already given in the data.

Thus, only subject remaining for $P$ is English.
Clearly, from the above table, the combination of subject and place of stay is not correct.
