A batsman makes 124 runs in his 21st inning and thereby increases his average by 4 runs. What is his average after 21 innings?
Answer & explanation
Correct answer: option 4
Extra runs score by him to increase average only is :
21 Inning × 4 (+ Avg.) = 84
Remaining 124 – 84 = 40 runs score to maintain previous average
⸫ Previous average = 40
New average = 40 + 4 = 44
