    In an examination, a student scores 4 marks for every correct answer and loses 1 mark for every wrong answer. If he attempts all 75 questions and secures 125 marks, the number of questions he attempts correctly is

    A) 35

    B)  40   

    C)  42

    D)  46

    Correct Answer: B

    Solution :

      Let the number of correct answer be \[x.\] Then, the number of wrong answer be \[75-x.\] According to the given condition, \[x\times 4-(75-x)\times 1=125\] \[\Rightarrow \]   \[4x-75+x=125\] \[\Rightarrow \]   \[5x=200\] \[\Rightarrow \]   \[x=40\]
