First find the number of five-room flats, then express as a percentage.<br><br>• Total flats = 200<br>• Four-room flats = 84<br>• Five-room flats = 200 − 84 = 116<br>• Fraction of five-room flats = \(\frac{116}{200}\)<br>• Simplify: \(\frac{116 \div 4}{200 \div 4} = \frac{29}{50}\)<br>• \(\frac{29}{50} \times 100\% = \frac{29 \times 100}{50}\% = \frac{2900}{50}\% = 58\%\)<br><br>Final Answer: 58
