Question 69

The daily average rainfall on 5 days of a week is 30 mm. If the rainfall on $$6^{th}$$ and $$7^{th}$$ day are 42 mm and 25 mm respectively, then what is the average daily rainfall for the 7 days?

Solution

Total rainfall for 5 days = 30 $$\times$$ 5 = 150 mm

Total rainfall for 7 days = 150 + 42 + 25 = 217 mm

Average rainfall for 7 days =$$\frac{217}{7}$$ = 31 mm

So, the answer would be option a)31
