The average score of a batsman in 20 innings is 42. If his highest score of 120 is excluded, what is the new average?

1. 37.89
2. 38.89
3. 39.89
4. 36.89

Correct answer: 37.89

Solution

The total score in 20 innings is \(20\times 42 = 840\). Excluding the highest score of 120 leaves \(840-120=720\), and the new average is \(720/19 \approx 37.89\).
