Question

The monthly rainfall in Bangalore for 6 months is given below. What is the average rainfall for those 6 months?
800 mm, 570 mm, 500 mm, 710 mm, 420 mm, 900 mm.

• A. 850 mm
• B. 625 mm
• C. 650 mm
• D. 710 mm

Answer 1

The correct option is C 650 mm

Given data,
800 mm, 570 mm, 500 mm, 710 mm, 420 mm, 900 mm.
Total rainfall = 800 + 570 + 500 + 710 + 420 + 900 = 3900 mm
Total number of months = 6
$\therefore$ Average rainfall = $\frac{\text{Total rainfall}}{\text{Number of months}}$
= $\frac{3900}{6}$
= $650mm$
