- Find his average score for the first 5 games.
- After his fifth game, his average score increased by 5.9 points. Find his score for his sixth game.
(a)
Total score of first 5 games
= 110 + 109 + 150 + 138 + 126
= 633
Average score of first 5 games
= 633 ÷ 5
= 126.6
(b)
Average score of 6 games
= 126.6 + 5.9
= 132.5
Total score of 6 games
= 6 x 132.5
= 795
Score of Vaidev's sixth game
= 795 - 633
= 162
Answer(s): (a) 126.6; (b) 162
