    B 160 Correct Answer Incorrect Answer
    C 150 Correct Answer Incorrect Answer
    D 170 Correct Answer Incorrect Answer
    E 159 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) + 150 = 180 0.25x = 180 – 150 0.25x = 30 x = 30/0.25 x = 120 Therefore, marks obtained by A = 1.25 × 120 = 150 marks
