Answer 1

Answer:

Option A: Number of circular divisions on them may be same

Explanation:

Least count of a screw gauge = Pitch/Number of circular division

Generally,

Pitch is 1 across all the screw gauge.

So for the two screw gauge to have similar least count, the number of circular division should be same
