    The batting average of 40 innings of a cricket player is 50 runs. His highest score exceeds his lowest score by 172 runs. If these two innings are excluded, the average of the remaining 38 innings is 48. His highest score was:

    A)  172                 

    B)         173                 

    C)         174             

    D)         176

    Correct Answer: C

    Solution :

    Total score of 40 innings \[=40\times 50=2000\] Total score of 38 innings \[=38\times 48=1824\] Let the highest score be x and the lowest score be y. Sum of the highest and the lowest score \[=x+y=2000-1824\] \[\Rightarrow \]   \[x+y=176\]                              ?...(i) and by question, \[x-y=172\]                   ?...(ii) Solving (i) and (ii), we get \[x=174\]
