How to solve the problem?
So as we can see, there was 99 rainy days and 67 days of high wind.
Now it is mentioned that there are 149 days in which one of the actions occurred.
so must formulate this problem as,
Days rained+ Days with the high wind - Days when both happened= 149
and now we will put the numbers over here.
99+67-X=149
X=99+67-149
X=17
So there are 17 days in total where there is both rain and high wind.
