Sorry R would be the south pole because of the reason:Q becomes the North pole, and R, where the magnet is lifted becomes the south pole.

Veda Dua from DPS R K PURAM, New Delhi
Class : Class 6
The magnet first makes contact with Q, so, it is the North Pole of the magnet

Jigishal Thool from Don Bosco School, Guwahati

AS NORTH POLE INTRODUCED AT Q PART OF THE IRON ROD SO Q WILL BE NORTH POLE.
