A batsman in his 17th innings makes a score of 85 and thereby increases his average by 3, his average after the 17th innings is : Correct Answer 37

Let the average of the first 16 innings be A. Total of the 16 innings = 16A New average = A + 3 New total of 17 innings, 17(A + 3) = 16A + 85 or,  17A + 51 = 16A + 85 or,  17A - 16A = 85 - 51 or, A = 34 So, new average after 17th innings = A + 3 = 34 + 3 = 37
