    your mathematics marks do not matter here just blindly do this calculation

    1) 4*your birth date
    2) +13
    3) *25
    4) -200
    5) +the month you were born
    6) *2
    7) -40
    8) *50
    9) +last two digits of the year you were born
    10) -10500

    and behold you get a number you are familiar with.

    awesome right?


    Enjoy !!!

    let's assume x as the date of birth, y as the month and z as the last two digits of the year



    1) 4*your birth date

    =4*x=4x

    2) +13

    =4x+13

    3) *25

    =(4x+13)*25=100x+325

    4) -200

    =100x+325-200 = 100x+125

    5) +the month you were born

    =100x+125+y

    6) *2

    =(100x+125+y)*2 = 200x+250+2y

    7) -40

    =200x+250+2y-40 = 200x+210+2y

    8) *50

    =(200x+210+2y)*50 = 10000x+10500+100y

    9) +last two digits of the year you were born

    =10000x+10500+100y+z

    10) -10500

    =(10000x+10500+100y+z)-10500

    =10000x+100y+z



    so basically what you have done is



    1)10000*your birth date + 100*the month you were born + last two digits of the year you were born



    soooooooooo boring
