After scoring 85 runs in the 17th innings, a batsman's average run increases by 3. What was his average before the 17th?
A
88 runs
B
82 runs
C
34 runs
D
37 runs
Correct Answer: 34 runs
Let the initial average be A. ATQ, 16 x A + 85 = 17 x (A + 3) or, 16A + 85 = 17A + 51 or, 17A - 16A = 85 - 51 or, A = 34 runs
