Two full turns of the circular scale of a screw gauge cover a distance of $1 \mathrm{mm}$ on its main scale. The total number of divisions on the circular scale is $50$. Further, it is found that the screw gauge has a zero error of $-0.03 \mathrm{mm}$. While measuring the diameter of a thin wire, a student notes the main scale reading of $3 \mathrm{mm}$ and the number of circular scale divisions, in line with the main scale, as $35$. The diameter of the wire is

• Correct answer
  A

  $\text{3.38} \mathrm{mm}$
• B

  $\text{3.32} \mathrm{mm}$
• C

  $\text{3.73} \mathrm{mm}$
• D

  $\text{3.67} \mathrm{mm}$

Hence, the correct answer is option: 'A'.
