The runs scored in 31st match are 103.

Given Data:

Average 30 matches=72 runs.

Average of $31^{\mathrm{st}}$ matched=73 runs.

To find:

Runs he made in the 31st match

Step 1:

First, find the total runs scored in 30 matches:  

Average = 72

Total Observations = 30

Sum of Observations = x

Step 2:

Using the below formulae.

Mean $=\frac{S u m \text { of observations }}{\text { No of Observations }}$

Step 3:

$=>72=\frac{x}{30}$

$\mathrm{X}=72 \times 30$

X=2160.

The runs scored in 31st match are 103.
