Step-by-step explanation:

4 must be subtracted from each of the numbers: 10, 12, 19 and 24, to get the numbers which are in proportion

So make an proportional eqn

(10-x) : (12-x) :: (19-x) : (24-x)

Bow interchange the values we got,

We get,

(10-x) : (24-x) ::(12-x) : (19-x)

By solving eqn

240-10x-24x :: 228 - 12x - 19x

240-228 ::34x-31x

12:3x

X=4

Diameter of a steel ball is measured using a Vernier caliper which has divisions of 0.1 cm on its main scale (MS) and 10 divisions of its Vernier scale (VS) match 9 divisions on the main scale. Three such measurements for a ball are (1) MSR = 0:5 cm, VSD = 8 (2) MSR = 0:5 cm, VSD = 4 (3) MSR = 0:5 cm, VSD = 6. If the zero error is 0:03 cm, then mean corrected diameter is 1. 0.53cm 2. 0.56cm...
