Description : A 20 m chain was found to be 10 cm too short after chaining 1000 m It was found to be 20 cm too short after chaining 1800 m. If the chain was correct before commencement of the work find the true distance.  

Last Answer : Average error in chain for 1000 m length = (0 + 10) / 2 = 5 cm = 0.05 m too short True length up to 1000 m = (20 - 0.05) x 1000 / 20 = 997.5 m. Average error in chain from 1000 m to 1800 m length = (10 ... 1800 m length = (20 - 0.15) x 800 / 20 = 794.0 m. True distance = 997.5 + 794 = 1791.5 m.
