    Answer: 30 

    Explanation:-
    Ratio of his marks in English and Mathematics is 2:3.
    Let his marks in English =2x,
    his marks in Mathematics =3x

    ‘A’ got twice as many marks in English as in Science
    his marks in English = 2 × His marks in Science
    his marks in Science =2×2=x

    Total marks = 180
    According to the Question,
    2x+3x+x=1806x=180x=30

    His marks in Science =x=30

    Hence, the answer is 30 .
