    B) 72       

    C) 80                    

    D) 96

    Correct Answer: C

    Solution :

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