A batsman in his 13th innings makes a score of 97 runs, thereby increasing his average score by 5. What is his average score after his 13th innings?
Answer & explanation
Correct answer: option 1
Extra runs score by him to increase average only is:
13 Inning × 5 (+ Avg.) = 65
Remaining 97 – 65 = 32 runs score to maintain previous average
⸫ Previous average = 32
New average = 32 + 5 = 37
