     \huge \boxed { \underline{ \bold{ \purple{A} \red{n} \blue{s} \green{w} \orange{e} \pink{r}}}}

    i) Class mark : upper limit + lower limit / 2

    = 10 + 5/2

    = 7.5

    ii) Class size : Upper limit – Lower limit

    = 10 – 5

    = 5

    .°. Class mark = 7.5 and

    Class size = 5

    {\underline{\boxed{\bf{\purple{★Solution:-}}}}}

    I) class mark : upper limit + lower limit /2

    = 10 + 5/2

    = 7.5

    II) class size : upper limit – lower limit

    = 10 – 5

    = 5

    Therefore,

    Class mark = 7.5

    Class size = 5
