Q11. What is the least count of a micrometer screw gauge if it has 50 divisions on its thimble scale and one complete rotation corresponds to 0.5 mm?
A0.01 mm
B0.02 mm
C0.05 mm
D0.1 mm
Correct Answer: A
The least count of a micrometer screw gauge is given by the pitch divided by the number of divisions on the thimble. Here, pitch = 0.5 mm, divisions = 50, so least count = 0.5 / 50 = 0.01 mm.

Q15. Express 0.612 in the form x/y, where x and y are integers and y ≠ 0.
A153/250
B61/100
C3/5
D6/10
Correct Answer: A
0.612 = 612/1000. Simplify by dividing numerator and denominator by 4: 612 ÷ 4 = 153, 1000 ÷ 4 = 250. 153 and 250 have no common factors (153=9×17, 250=2×5³). Thus, 153/250.
