Explanation:

Let’s break this down simply:

- The batsman’s average in the first 7 matches is 53. So, total runs = 7 × 53 = 371.

- In the other 9 matches, his average is 33. So, total runs = 9 × 33 = 297.

- Total matches played = 16. Total runs = 371 + 297 = 668.

- To find the average: 668 runs ÷ 16 matches = 41.75.

Let’s check your options:

1. 41.75 

2. 44.25 – Not possible; the calculation doesn’t support this.

3. 47 – That would require more runs per game overall than the actual numbers.

4. 49.175 – Same issue, too high.

?? So the correct answer is option 1: 41.75.
