Question

    The marks obtained by A is 25% more than B, and the

    marks obtained by C is 160 more than the difference of the marks obtained by A and B. If C obtained 175 marks, then find the marks obtained by A.
    A 70 Correct Answer Incorrect Answer
    B 76 Correct Answer Incorrect Answer
    C 75 Correct Answer Incorrect Answer
    D 72 Correct Answer Incorrect Answer

    Solution

    Let the marks obtained by B be ‘x’. So, marks obtained by A = 1.25x According to question, (1.25x – x) + 160 = 175 0.25x = 175 - 160 0.25x = 15 x = 15/0.25 x = 60 Therefore, marks obtained by A = 1.25 × 60 = 75 marks
