A cricketer whose bowling average is 12.4 runs per wicket takes 5 wickets for 26 runs and thereby decreases his average by 0.4. The number of wickets taken by him till the last match was-
Suppose, the number of wickets taken by him until last match was
New average is
total run conceded after the last match =
run conceded before last match =
So, average =
According to the question,
Let the number of wickets taken by bowler after the match be N.
So, number of runs given by bowler after match =(N−5)×12.4 +26
=12.4N−62+26
=12.4N−36
Average of bowler after match =
As per question , average of bowler after match =12.4−0.4=12
Equating both averages , we get
= 12
12.4N−12N = 36
N =
N=90
So, Number of wickets taken by bowler till last match =N−5=90−5=85
