Let the average of the batman in the first 11 innings be x. The total run scored by the batsman in the first 11 innings = 11 x x = 11x The total run scored by the batsman in all 12 innings = 11x + 84 New average score after 12th innings = x + 4 According to the question, (11x +84)/12 = (x + 4) (11x +84) = (x + 4) x 12 11x +84 = 12x + 48 12x-11x = 84-48 x = 36 Now, x + 4 = 36 + 4=40 40 is the average score per innings of the batsman after the 12th innings.
