The correct answer is option (B):
28.9
To determine the correct answer, we need additional information that is not provided in the original prompt. The prompt only gives the question and the options. Without the data for the player's performance in each match, or at least summary data, such as runs scored, number of matches played, and average, we cannot perform the calculation required to determine the new average.
To calculate the new average, we would need the following steps:
1. Understand the initial data: We would need information about the player's total runs and matches played *before* the adjustments. This could be in the form of his average (runs/match) across the 250 matches, or the total runs scored.
2. Identify matches against Pakistan in 2005 and South Africa in 2007: We would need data showing how many matches were played against Pakistan in 2005 and South Africa in 2007. The total number of runs scored in these matches would also be important.
3. Adjust the totals:
* If we know the player's average, we can find the total runs he scored by multiplying the average by the number of matches.
* Subtract the runs scored against Pakistan in 2005 and South Africa in 2007.
* Subtract the number of matches played against Pakistan in 2005 and South Africa in 2007 from the total number of matches (250).
4. Recalculate the average: Divide the adjusted total runs by the adjusted number of matches.
Without the initial performance data and match specific information, we can't perform any calculations and are unable to definitively pick a correct answer. However, assuming that the provided correct answer of 28.9 is based on the missing initial data, this is the expected method for determining a correct answer.
