IMO B

1 game z points
q game zq points

100 points in next game

$$\frac{zq + 100}{q + 1}$$

E $$\frac{z + 100}{q + 1}$$

Total points = zq

100 points must be added to zq.

number of games must be q + 1

Average; zq + 100/q +1

sum of scores before 100 point game = zq
zq+100/ q+1 ; new avg

IMO B
