Hello friend,
Your quetion is slightly incomplete.

◆ Correct question is -
A vernier has 10 division and they are equal to 9 divisions of main scale in measurement. Scale is calibrated in mm. What is its least count?

◆ Answer-
LC = 0.1 mm

◆ Explaination-
# Given-
1 MSD = 1 mm
1 VSD = 9/10 mm = 0.9 mm

# Solution-
Least count of vernier calliper is -
LC = 1 MSD - 1 VSD
LC = 1 - 0.9
LC = 0.1 mm

Least count of vernier calliper is 0.1 mm.
