Question

The given table shows the rainfall (in mm) in different cities in India for an year.

$\begin{array}{cc}\text{Cities}& \text{Rainfall (mm)}\\ \text{Delhi}& 44.6\\ \text{Mumbai}& 63.5\\ \text{Kolkata}& 60.7\\ \text{Pune}& 56.2\\ \text{Bangalore}& 60.1\\ \text{Bhubaneswar}& 49.4\\ \text{Chennai}& 61.7\\ \text{Ooty}& 56.9\\ \text{Ahmedabad}& 34.4\\ \text{Jaipur}& 32.5\end{array}$

Find the Mean rainfall (in mm) for the year.

• A. 55
• B. 53.5
• C. 52
• D. 50.25

Answer 1

The correct option is C

52

The number of cities given are 10

The sum of rainfalls = 44.6 + 63.5 + 60.7 + 56.2 + 60.1 + 49.4 + 61.7 + 56.9 + 34.4 + 32.5 = 520

Mean = $\frac{Sumofobservations}{Numberofobservations}$

= $\frac{520}{10}$

= 52
