Question

The pitch of a screw gauge is 1mm and there are 50 divisions on its cap. When nothing is put in between the studs , 44th division of circular scale coincides with reference line. When a glass plate is placed between the studs, the main scale reads three divisions and the circular scale reads 26 division. The thickness of the plate is-
