Correct Answer: B
Solution :
Flats with fewer than 4 occupants are those with 1, 2 or 3 occupants. Number of flats with fewer than 4 occupants \[=2+5+8=15\] Total number of flats \[=2+5+8+14+12+9+4=54\] Percentage of flats with fewer than 4 occupants \[=\frac{15}{54}\times 100%\] \[=27.8%\] (3 significant figures)You need to login to perform this action.
