A 30 m chain after measuring a distance of 6000 m was found to be 10 cm more than the designed length. If the chain was standardised before the commencement of survey then the true length is
- A6020 m
- B6010 m
- C5990 m
- D5980 m

Measured distance = 6000 m
Error in chain = $(\frac{{10}}{100} = 0.1\;m\;)$
∴ Actual or true distance = Measured distance x (1 + e/L)
$(= 6000 \times \left( {1 + \frac{{0.1 }}{{30}}} \right))$
= 6020 m
