screw gauge of pitch 0.1 cm and 50 divison on circular scale measure thickness of object which of following measurement is possible for thickness

The pitch of a screw gauge is 0.5 mm and there are 50 divisions on the circular scale. In measuring the thickness of a metal plate, there are five divisions on the pitch scale (or main scale) and thirty fourth divisions coincide with the reference line. Calculate the thickness of the metal plate.

pitch of screw gauge is 1 mm and it has 100 divisions on circular scale . There is no zero error. Thickness of a pile of 50 papers is to be found out . While measuring the thinckness of a paper it is observed that linear scale does not give any reading but 25 ^(th) circular scale divsion coincides with reference line , thinkness of pile is -
