    D 400 Correct Answer Incorrect Answer

    Solution

    Let the total available marks in the examination be 100x. Marks scored by A = 42% of 100x = 42x Marks scored by B = 72% of 100x = 72x According to question, => 42x + 60 = 72x – 90 => 30x = 150 => x = 5 Total marks of the examination = 100x = 500
