| Understanding | Application |
|
Calculate total run of 12 matches and then calculate total run of 8 matches by subtracting total run of 12 matches from the total score. Average = Total Run / Number of matches |
Average = Total Run / Number of matches 35 = Total Run/20 Total run = 35 x 20 = 700 Average of 12 matches = Total Run of 12 matches / Number of matches 45 = Total Run of 12 matches/12 Total run of 12 matches = 12 x 45 = 540 Total run of 8 matches = 700 - 540 = 160 Average of 8 matches = 160/8 = 20 |
