A batsman had an average of 42.8 over 15 innings. In his
next three innings, he made 55, 103, and 47 runs. What is his updated batting average?Solution
ATQ,
Runs scored by batsman till 15 innings = 42.8 × 15 = 642 Total runs after next 3 innings = 642 + 55 + 103 + 47 = 847 So, new average = 847 ÷ (15 + 3) = 47.05
