    Here is my answer brainly dear

    Step-by-step explanation:

    <body bgcolor=brown>

    <font color=lime>

    <center>

    Let ,

    Number of boys = 10x

    Number of girls = 7x

    \underline\blue{According~to~the~condition} \bf\green{:-}

    • 10x = 7x + 6
    • 10x 7x = 6
    • 3x = 6
    • x = \frac{6}{3}
    • x = 2

    :. Number of boys = 10x = 10 × 2 20

    Number of girls = 7x = 7 × 2 14

    Therefore ,

    Total strength = Number of boys + Number of girls

    Total strength of the class = 20 + 14 = 34

    \huge\rm\underline\pink{GIVEN:}

    • \large\rm{Ratio\:of\:boys\:and\:girls:=\:10:7}
    • \large\rm{Number\:of\:boys\:=\:6+Number\:of\:girls}

    \huge\rm\underline\pink{TO\:FIND:}

    • \large\rm{Total\:strength\:of\:class}

    \huge\rm\underline\pink{SOLUTION:}

    \large\rm{Let\:Number\:of\:girls\:be\:7x}

    \large\rm{Let\:Number\:of\:boys\:be\:10x}

    \large\rm{Number\:of\:boys\:=\:Number\:of\:girls\:+6}

    \large\rm{\implies{7x+6\:=\:10x}}

    \large\rm{\implies{3x\: =\:6}}

    \large\rm{\implies{x\:=\:2}}

    \large\rm{Number\:of\:girls\:=\:7x\:=\:14}

    \large\rm{Number\:of\:boys\:=\:10x\:=20}

    \large\rm{Total\:strength\:=\:Number\:of\:boys+Number\:of\:girls}

    \large\rm{\therefore{Total\:strength\:of\:class\:=\:14+20\:=\:34}}
