- The average of runs scored by 8 players is 55.

- Total runs = Average × Number of players = 55 × 8 = 440.

- Runs scored by 7 players: 25, 35, 45, 60, 65, 60, 80.

- Sum of runs scored by 7 players = 25 + 35 + 45 + 60 + 65 + 60 + 80 = 370.

- Runs by 8th player = Total runs - Sum of runs by 7 players = 440 - 370 = 70.
