    math quiz


    a boy was very naughty

    his teacher gave him an assignment to keep him busy

    that is add all the numbers from 1 to 100

    in couple of minutes he came back with the answer 5,050

    that is he multiplied 50 * 101

    how he came up with 50 and 101 numbers

    is given below

    1+100 = 101
    2+99 = 101
    3+98 =101
    4+97 =101
    :
    :
    :
    52+49 = 101
    51+50 = 101

    so there are 50 pairs of 101 number
