    Answer:

    The number of positive integral solutions of the equation x

    1

    +x

    2

    +x

    3

    +….+x

    r

    =n is

    n−1

    C

    r−1

    . ⋅ The number of non-negative integral solutions of the equation x

    1

    +x

    2

    +x

    3

    +….+x

    r

    =n is

    n+r−1

    C

    r−1

    .

    Required number of non-negative integral solution is =

    10+3−1

    C

    3−1

    =

    12

    C

    2
