Question 595916
If a man and a half can build a house and a half in a day and a half.
How many houses can 3 men build in a week and a half.
-----------
1.5 houses take 1.5*1.5 man-days
3 men is 2x
--> 3 houses in 1.5 days
1.5 weeks is 7x
--> 21 houses
==============
1.5 houses = 2.25 man-days
--> 1.5 man-days per house
3 men * 10.5 day = 31.5 man-days
31.5/1.5 = 21 houses
