(iii) R does not stay as PG and studies Philosophy.

(iv) The students studying Statistics and History do not stay as PG.

(v) T studies Mathematics and S studies Physics.

(vi) U and S stay in hostel. T stays as PG and Q stays at home.

Which of the following pairs of students stay at home ?

• A. PQ
• B. QR
• C. RS
• D. ST
• E. None of these

Answer 1

The correct option is B QR

(i)

R does not stays as PG.

T stays as PG.

U and S stays in Hostel.

Q stays at home, so P stays as PG.

R stays at home.

(ii)

R studies Philosophy.

T studies Maths and S studies Physics.

Since P stays as PG, Q and U studies either Statistics or History.

Only P's subject of study is remaining.

So, P studies English.

Clearly, QR stays at home.
