A batsman has a certain average of runs for 16 innings. In the 17th innings he makes a score of 85 runs, thus increasing his average by 3 runs. What is the average of the batsman after the 17th innings?
A35
B37 ✓ Correct
C45
D40
Correct answer: (B) 37
Explanation
The new average is 37 runs.
Let the average of 16 innings be x, total = 16x.
After 17th: (16x + 85) / 17 = x + 3.
16x + 85 = 17x + 51, so x = 34.
New average = 34 + 3 = 37.
