Answer 2

Answer:

The average of the results is 24.

Step-by-step explanation:

It is given that the average of 30 results is 20.

Total score of 30 results = $30\times 20=600$

Average of other 20 result is 30.

Total score of 20 results = $20\times 30=600$

Total number of results = $20+30=50$

Total score = $600+600=1200$

$Average=\frac{\text{Total score}}{\text{Total number of results}}$

$Average=\frac{600+600}{50}$

$Average=\frac{1200}{50}$

$Average=24$

Therefore, the average of the results is 24.
