Question

Rainfall of a town in a week is 4 cm, 5 cm, 12 cm, 3 cm, 6 cm, 8 cm, and 4 cm, then the average rainfall per day is:

• A. 4 cm
• B. 5 cm
• C. 6 cm
• D. 7 cm

Hint:

To find the average, sum the values and divide by the number of days (or observations).

Answer 1

The Correct Option is B

To find the average rainfall per day, first calculate the total rainfall in the week: \[ \text{Total rainfall} = 4 + 5 + 12 + 3 + 6 + 8 + 4 = 42 \, \text{cm} \] Now, divide the total rainfall by the number of days in a week (7 days): \[ \text{Average rainfall per day} = \frac{42}{7} = 6 \, \text{cm} \] Thus, the correct answer is option (3).
