    Let the total number of puris be x, and the plates be y.

    From the first given, if she places 4 puris in each plate, one plate would be missing. If we put these words into an equation:

       (1)

    From the second given, if she places 3 puris in each plate, 1 puri will be given. If we put these words into an equation:

        (2)

    From equations (1) and (2):

    Therefore, the number of plates is 5.

    Now solve for x: 

    Therefore, the number of puris is 16.
