The average score of 24 is 84, and four is more than two books 10.

That is two plus four = 84 * 2 =168; Four-two = 10 is transformed into a sum-difference problem.

So four =( 168+ 10)/2=89.

Two =( 168- 10)/2=79.

Average score 14 =86

So, one =86*2-89=83.

The average score is 9 1.5,

So, three =9 1.5*2-83= 100.

So, five =89*5-83-79- 100-89=94.
