Hi Dhiraj.. Could you check this question , i wasn't getting the answer when i tried to solve it by the method you used for Q14. Q) The bowling average of a cricketer was 12.4. He improves his bowling average by 0.2points when he takes 5 wickets for 26 runs in his last match . The number of wickets taken by him before the last match was ? and one more question is , if the average bowling speed improves means , should we subtract or add that 0.2 to 12.4 ?

175 wickets + 5 wickets in last match = 180 wickets in total

You will have to subtract 0.2 from 12.4 because here improvement means reduction in runs per wicket
AC
185 -5 as asking (wickets taken by him before the last match )..equal to 180
