    A cricketer whose bowling average is 24.85, runs per wicket, takes 5 wickets for 52 runs and thereby decreases his average by 0.85. The number of wickets taken by him till the last match was

    A)  64                   

    B)  72   

    C)  80       

    D)  96

    Correct Answer: C

    Solution :

    Let the number of wickets taken till the last match be n. \[\therefore \]Total runs at the rate 24.85 runs per wicket = 24.85 n Total runs after the current match = 24.85 n + 52 Total number of wickets after the current match = n + 5 Bowing average after the current match \[=\frac{24.85n+52}{n+5}=24.85-0.85\] \[\therefore \]      \[\frac{24.85n+52}{n+5}=24\] \[\Rightarrow \]\[24.85n+52=24n+120\] \[\Rightarrow \]\[0.85n=120-52\,\,\,\,\,\Rightarrow \,\,n=\frac{68}{0.85}=80\]
