The number of days which had good weather = 12

Explanation:

3 weeks has 7xx3 =21 days

Given: A fine day occurred on more than 3 days than the days which rained.

If the number of days on which it rained =x, then

The number of fine days = 3+x

Total number of days = fine days + rainy days = x+3 +x =21

=> 2x +3 =21

=> 2x=18

=> x= 9

So, the number of day it rained were =9

The number of days which had good weather = 21-9= 12
