Q1. A batsman has a certain average of runs for 16 innings. In the 17th innings, he makes a score of 85, thereby increasing his average by 3. What is his average after the 17th innings?
Answer: 33
Explanation: Let the average after 16 innings be x. Then total runs = 16x. After 17th innings, total runs = 16x + 85 and average = x + 3. So, (16x + 85) / 17 = x + 3.
