a) First game = x
Second game (median) = 8
Third game (7 more than first) = x+7
Mean of all three games = 9
x+x+7+8/3 = 9
2x+15 = 27
2x = 12
x = 6 (First game)
Second game = 8
Third game = x+7 = 6+7 = 13

b) Mean of four games = 11
scores of four games/no. of games = mean
Score of fourth game = x
6+8+13+x/4 = 11
27+ x = 11
x = 17 (Fourth game)
