Yang Bobo farmed for 20 A Mu days in sunny days and only worked for 12 A Mu days in rainy days. He plows eight days a year, plowing 1 12 mu. How many sunny days are there these days?
Solution:

Suppose there are x days in sunny days and 8-x days in cloudy days.

20x+(8-x)× 12 = 1 12

20x+96- 12x = 1 12

8x = 1 12 - 96

8x = 16

x = 2

That is:

2 sunny days and 6 cloudy days.
