A vernier calipers and a screw gauge have the same least count and zero error with the difference that the vernier calipers has positive zero error and the screw gauge has negative zero error The number of circular scale divisions on the screw gauge is twice the number of vernier scale divisions on the vernier calipers and the pitch of the screw gauge is 1 mm If the vernier coinciding division and the circular scale reading for the zero error on the instruments are 3 and 97 respectively then find the number of vernier scale divisions on the vernier
