    Solution

    ATQ,

    Total marks in all three subjects = 95 ├Ч 3 = 285

    Marks in Economics and Business Studies = 285 тАУ 105 = 180

    Let the marks in Business Studies be тАШxтАЩ.

    Then marks in Economics = 1.4x

    x + 1.4x = 180

    2.4x = 180

    x = 180 / 2.4

    x = 75

    So, marks in Business Studies = 75 marks
