Answer:

The question is not proper

Step-by-step explanation:

Answer 2

number of buildings=4

floors in each building=15

no of sold flats=4

total number of flats=15X4

                                 =60

                                 =60X4

                                 =240

                                 =240-4

                                 =236

Thus,there are 236 flats empty and 240 flats in total
