B took five more than C.

A got 8 more than B, which means 13 more than C.

In this way, Party A and Party B always get 18 more than Party C. ..

This 18 was originally divided equally, and each person took six.

Now C didn't take it, B took 5, and A took 13.

In this way, all six of C were given to A, and A paid C 7.2 yuan. The first table tennis 1.2 yuan can find it.

B only got five, but failed to get 1. 1 table tennis was also given to a .. so a has to give b the price of a ball. That is 1.2 yuan.

Do you understand?
