Question

Measurement made in science lab must be as accurate as possible. Ravi measured the length of an iron rod
and said it was 19.34 cm long; Kamal said 19.25 cm; and Tabish said 19.27 cm. The correct length was 19.33
cm. How much of error was made by each of the boys?

Answer 1

$\blue✭\pink{ Required \: Solution}\blue✭$

$\orange{The \: correct \: length \: of \: the \: iron \: rod = 19.33 \: cm}$

$\green {The \: length \: of \: the \: rod \: measured \: by \: Ravi = 19.34 \: cm}$

$\red {Error \: made \: by \: Ravi = (19.34 - 19.33) \: cm = + 0.01 \: cm}$

$\green{ The \: length \: of \: the \: rod \: measured \: by \: Kamal = 19.25 \: cm}$

$\red {Error \: made \: by \: Kamal = (19.25 - 19.33) \: cm = - 0.08 \: cm}$

$\green{ The \: length \: of \: the \: rod \: measured \: by \: Tabish = 19.27 \: cm}$

$\red {Error \: made \: by \: Tabish = (19.27 - 19.33) \: cm = -0.06 \: cm}$
