Which of the following pairs of students stay. One each at hostel and at home?

• A. QR
• B. SR
• C. US
• D. Data indequate.
• E. None of these

Answer 1

Answer: (B)

SR

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

From 5th and 6th 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 is hostel and Q stays at home from 6th statement. Thus these both can only be doing Statistics/History because the remaining candidate Q, stays at home. Thus, only subject remaining for Q is English.
