Question

A 30 meter metric chain is found to be 0.1 meter too short throughout the measurements.if the distance is recorded as 300 meter then the actual distance will be

Answer 1

hi!!here is your answer.._________________________
______________
Actual length of chain = 30 - 0.1 = 29.9m

True length of chain(L) x True length of distance(l) = wrong length of chain(L') x wrong length of distance (l')

              30  x  True length of distance = 29.9 x 300

                        True length of distance = 29.9 /30 x 300 = 299 m
