Let the no. of wickets taken beforethe last match be n. Total runs at 28.25 runs per wickets = 28.25n Total runs after the current match = 28.25n + 73 Total no. of wickets after the current match = n + 2 Bowling average after the current match ⇒ (28.25n + 73 )/(n + 2) = 28.25 + 0.75 ⇒( 28.25n + 73 )/ (n + 2) = 29 Or, 28.25n + 73 = 29n + 58 Or, 0.75n = 73-58 Or, n = 15/.75 = 20
