If it rain 20% of the time out of 60 day, how many days did it not rain?
Answers (2)
1% literally means: one per hundred.
1% = 1 / 100 = 0.01
20% of 60 means
20/100 * 60 = 0.2 * 60 = 12
Thus, it's raining 12 days. In total there are 60 days. And the question is:
how many days did it not rain?
60 - 12 = 48
So, it's not raining for 48 days.
Well, in order to satisfy the notorious stickler, it's not raining for the time equivalent to 48 days ;)
