2.13 mm


Option: 2

2.23 mm

The total reading of the screw gauge is given by the sum of the main scale reading, the product of the pitch and the number of complete rotations of the thimble scale, and the product of the pitch and the thimble scale reading divided by the number of circular scale divisions:

\text{Total reading} = 2 \text{ mm} + 0.5 \text{ mm} \times 0 \text{ rev} + \frac{0.5 \text{ mm}}{50} \times 25 = 2.25 \text{ mm}

Therefore, the thickness of the sheet is 2.25 mm, which is option (3).
