A batsman has a certain average runs for 20 innings. In the 21" inning...
Given data:
- Average runs for 20 innings = x
- Runs scored in the 21st innings = 107
- Increase in average = 2
Calculation:
- Total runs in 20 innings = 20x
- Total runs after 21 innings = 20x + 107
- Average after 21 innings = Total runs after 21 innings / 21
Explanation:
Step 1: Calculate total runs after 21 innings
- Total runs after 21 innings = 20x + 107
Step 2: Calculate average after 21 innings
- Average after 21 innings = (20x + 107) / 21
Step 3: Substitute the given values
- Given, increase in average = 2
- Therefore, (20x + 107) / 21 - x = 2
Step 4: Solve for x
- (20x + 107) - 21x = 42
- -x + 107 = 42
- x = 107 - 42
- x = 65
Step 5: Calculate average after 21 innings
- Average after 21 innings = (20*65 + 107) / 21
- Average after 21 innings = (1300 + 107) / 21
- Average after 21 innings = 1407 / 21
- Average after 21 innings = 67
Therefore, the batsman's average after 21 innings is 67.
- Average runs for 20 innings = x
- Runs scored in the 21st innings = 107
- Increase in average = 2
Calculation:
- Total runs in 20 innings = 20x
- Total runs after 21 innings = 20x + 107
- Average after 21 innings = Total runs after 21 innings / 21
Explanation:
Step 1: Calculate total runs after 21 innings
- Total runs after 21 innings = 20x + 107
Step 2: Calculate average after 21 innings
- Average after 21 innings = (20x + 107) / 21
Step 3: Substitute the given values
- Given, increase in average = 2
- Therefore, (20x + 107) / 21 - x = 2
Step 4: Solve for x
- (20x + 107) - 21x = 42
- -x + 107 = 42
- x = 107 - 42
- x = 65
Step 5: Calculate average after 21 innings
- Average after 21 innings = (20*65 + 107) / 21
- Average after 21 innings = (1300 + 107) / 21
- Average after 21 innings = 1407 / 21
- Average after 21 innings = 67
Therefore, the batsman's average after 21 innings is 67.
