The solution shown by the other tutor is a standard solution method.

Here is a different method you can try to see if you like it....

The difference between the two averages is 6; that means in the first 10 games her total score was 10*6 = 60 short of the new average.

That means the 11th score has to be 60 points above the new average.

ANSWER: Her score in the 11th game was 310+60 = 370.
