Question
A batsman in his 17th innings makes a score of 85, and thereby increases his average by 3. What is his average after 17 innings?
Answer: Option B
- Let the average after 16th innings be a, then total score after 17th innings =>
16a+85 = 17 (a+3)
a = 85-51 = 34
Average after 17 innings = a + 3 = 34 + 3 = 37
