    Ram got twice as many marks in English as in Science. His total marks in English, Science and Maths are 180. If the ratio of his marks in English and Maths is 2 : 3, what are his marks in Science?

    A) 30

    B) 60

    C) 72

    D) 90

    Correct Answer: A

    Solution :

    [a] Let marks got by Ram in Science \[=x\] Then, marks in English \[=2x\] \[\therefore \] Marks in Maths \[=3/2\times 2x=3x\] Now, total marks got by Ram \[=180\] \[\therefore \]      \[x+2x+3x=180\] \[\Rightarrow \]   \[x=\frac{180}{6}=30\]
