(c) ?Write a short note on mistakes in chaining. [4)
[d] A 30 m chain was tested before the comnencement ofthe day's work and [4}
was found to be correct. After chaining a distance of 100 chain: it was
found to be 5 cm too short. At the end of day's work after chaining a total
distance of 180 chains. the chain was found to be 10 cm too long, ?o?fhat
was the true distance chained?
