In a cubic system P atoms occupy all the corners. Q atoms occupy face ...
The formula representation P2Q3R4 tells us that there are 2 P atoms, 3 Q atoms, and 4 R atoms in the unit cell of this cubic system.

In a cubic system, there are a total of 8 corners, 6 face centers, and 12 edge centers.

Since there are 2 P atoms in the unit cell, and each corner is occupied by 1 P atom, all 8 corners are occupied by P atoms.

Since there are 3 Q atoms in the unit cell, and each face center is occupied by 1 Q atom, all 6 face centers are occupied by Q atoms.

Since there are 4 R atoms in the unit cell, and each edge center is occupied by 1 R atom, all 12 edge centers are occupied by R atoms.

Therefore, the percentage of face centers occupied by Q atoms is (6/6) * 100% = 100%.

The percentage of edge centers occupied by R atoms is (12/12) * 100% = 100%.

So the correct answer is (A) 100%.
