So the total score. A in a4 1b is less than 4.
36=4×9, so this total score can be divisible by both 4 and 9.
According to the characteristic that numbers can be divisible by 4 and 9 at the same time,
a=2,b=2。
That is, the total score is 24 12,
Then the average score is: 24 12÷2=67 (points).
A: The average score of each player is 67 points.
