    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:

    A)  64                               

    B)  72

    C)  80                     

    D)         85                          

    Correct Answer: D

    Solution :

    Let the number of wickets taken till the last match be x. Then, \[\frac{12.4x+26}{x+5}=12\Rightarrow 12.4x+26=12x+60\] \[\Rightarrow \]   \[0.4x=34\Rightarrow x=\frac{34}{0.4}=\frac{340}{4}=85\].
