A screw gauge has main scale divisions of 1 mm each and its circular scale has 50 division. While measuring the diameter of a ball, cap end is after `19^("th")` marking of main scale and `21^("st")` division of circular scale coincides with the reference line. What is the measured diameter diameter of the ball?
