Question #90154

Answer 1

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`
