    Given :

    • Ratio of the number of boys to girls in a school is 2:5.
    • Total no. of students in school = 350

    To Find :

    • Number of girls in the school.

    Solution :

    \longmapsto\tt{Let\:no.\:of\:boys\:be=2x}

    \longmapsto\tt{Let\:no.\:of\:girls\:be=5x}

    \longmapsto\tt{Total\:Students=350}

    A.T.Q :

    \longmapsto\tt{2x+5x=350}

    \longmapsto\tt{7x=350}

    \longmapsto\tt{x=\cancel\dfrac{350}{7}}

    \longmapsto\tt\bold{x=50}

    Therefore :

    \longmapsto\tt{No.\:of\:boys=2(50)}

    \longmapsto\tt\bold{100}

    \longmapsto\tt{No.\:of\:girls=5(50)}

    \longmapsto\tt\bold{250}

    _______________________

    VERIFICATION :

    \longmapsto\tt{2(50)+5(50)=350}

    \longmapsto\tt{100+250=350}

    \longmapsto\tt\bold{350=350}

    Answer:

    2x * 5x=350

    10x=350

    x=350

    10. =35

    no.of boys =35*2=70

    no. of girls=35*5. =175
