Explanation / Answer

1) Main scale reading is 5 and each division is 1/16 it intersects the vernier scale at 15 divsion so reading becomes 5 15/16 therfore correct option is (c) 5 15/16

2) Main scale reading is 1 then mini scale reading is 0.975 and vernier reading intersect at zero therfore reading becomes 1+.975= 1.975 correct option is (c) 1.975

3) Main scale reading is 3 and intersects mini scale at .45 and vernier scale at 16 position and since vernier is in thousand of inches ot becomes 16/1000=0.016 and reading becomes 3+0.45+.016=3.466 correct option is (d) 3.466

4) Main scale reading is 0 mini scale reads 0.9 and vernier intersects at 11 division which means 0.011 therefore reading becomes 0+0.9+0.011=0.911 therefore correct option is (e) 0.911
