The least count of a vernier callipers P and Q, 1 MSD = 1 mm. For P, 10 VSD + 8 MSD and for Q, 20 VSD = 15 MSD. The vernier callipers that gives more accurate reading is _______________.

For each of the two vernier callipers P and Q, 1 MSD = 1mm. For P, 10 VSD = 8 MSD and for Q, 20 VSD = 15 MSD. The vernier callipers that gives more accurate reading is ____________.

In a vernier calipers, if 1 M.S.D. = 0.1 cm and the least count is 0.1 mm, then 1 V.S.D = 0.9 mm

The least counf of a vernier calipers having 20 vernier divisions when 1 M.S.D. =0.1 cm is "______" cm.

The following information is given in respect of a vernier calipers. 1 main scale division = 0.3 cm 30 V.S.D. = 29 M.S.D. The least count of this vernier calipers is ______________.

The least count of vernier callipers is 0.1 mm . The main scale reading before the zero of the vernier scale is 10 and the zeroth division of the vernier scale coincides with the main scale division. Given that each main scale division is 1mm . The measured value should be expressed as
