    Answer: Option 'A'

    Let the marks secured by them be x and (x + 9)

    Then sum of their marks = x + (x + 9) = 2x + 9

    Given that (x + 9) was 56% of the sum of their marks

    =>(x+9) = 56/100(2x+9)

    =>(x+9) = 14/25(2x+9)

    => 25x + 225 = 28x + 126

    => 3x = 99

    => x = 33

    Then (x + 9) = 33 + 9 = 42

    Hence their marks are 33 and 42
