The true length of a line is known to be 200 m. when this is measured with a 20 m tape, the length is 200.80 m. The correct length of the 20 m tape is
  • a)
    19.92 m
  • b)
    19.98 m
  • c)
    20.04 m
  • d)
    20.08 m
Correct answer is option 'A'. Can you explain this answer?

True length = 200 m. tape length= 20 m measured length= 200.80 m Error = 200.80 - 200 = .80 m because tape will be used 10 times for measuring actual length thatswhy .80 will be divided in 10 parts which will be .08 so tape length would be 20 - .08 =19.92 m.
