Hint: To find the correct observed reading we need to find the least count first, Least count is the smallest value that can be measured by the measuring instrument.

Complete step by step solution:
$LC = MSD - VSD$ is called lowest number or vernier constant. This is the shortest length that can be accurately measured with Vernier calipers. For the given vernier calipers.
The formula for writing the observed reading is, observed reading=$M.S.R.+V.S.D. \times L.C.$

Note the number (n) of the vernier scale division that coincides with the division of the main scale. We should repeat steps 5 and 6 after measuring the diameter in the vertical direction by the body to 90, repeat steps 4 to 7 for three different positions and record the observations. Now find the total readings using the equation, $TR = MSR + VSR = N + (N \times LC)$ and apply the zero correction. Find the mean of different values ​​of diameter and show the result with the appropriate unit.
