While in Canada, I visited a beautiful high-rise building in the Metropolitan City of Toronto. The manager of the building told me that the building consisted of different kinds of apartments large and small. Two room apartments were 5% in number, 21/2's-7% in number, 3's-15% in number, 31/2's-20% in number, 41/2's-49% in number, 5's-33% in number, 51/2's-12% in number, 6's-3% in number and in addition several 4 room apartments. Altogether the building contained 437 apartments.

Can you figure out how many apartments are there in each type, using round figures?

--- the percentages add up to `144% do we have to convert it base first .. i've no clue how to go abt it

If on this basis we temporarily exclude appartments with 1/2 rooms, we see that 4 room appartments will account for the remaining 44% (= 100 - 5 - 15 - 33 - 3).

The (whole) number of appartments for each category is then :

2 22

21/2 31

3 66

31/2 87

4 192

41/2 214

5 144

51/2 52

6 13

That doesn't make sense, since the number of 2 1/2 exceeds the number of 2, and the number of 3 1/2 exceeds the number of 3

Andy : so if the percentages are in base 8 and the figures given already total 144%, how can there be any extra 4room appts ? also I would say that "perCENTage" implies base 10

I live in Switzerland, my first flat here was a 2 1/2 room flat later followed by a 3 1/2 room. The 1/2 is used to indicate separate or combined kitchen/dining areas.
