Answer:
5 Days
Step-by-step explanation:
If the rainfall (in mm) in a city on 7 days of a certain week was recorded as 0, 12.2, 2.1, 0, 20.5, 5.5, 1 then the number of days less than the mean rainfall:
Daily Rain Fall for 7 Days
0 , 12.2 , 2.1 , 0 , 20.5 , 5.5 , 1
Total Rain fall = 0 + 12.2 + 2.1 + 0 + 20.5 + 5.5 + 1 = 41.3
Total Days = 7
Mean Rainfall = 41.3/7 = 5.9
0 , 2.1 , 0 , 5.5 , 1 are less than 5.9
so 5 Days - Rains was less than Mean rainfall
option C is correct
