\boxed{ \pmb )/(actual) * 100 }

  • Approx = 80
  • Actual = 75.75


\sf\% \: error = ( |80 - 75.75| )/(75.75) * 100


\sf\% \: error = ( |4.25| )/( (303)/(4) ) * 100


\sf\% \: error = ( 4.25 )/( (303)/(4) ) * 100


\sf\% \: error = ( (17)/( \cancel4) )/( (303)/( \cancel4) ) * 100


\sf\% \: error = ( 17 )/( 303 ) * 100


\sf\% \: error = ( 1700 )/( 303 )


\sf\% \: error = 5.6\%

  • Difference=80-75.75=4.25"

Error


\\ \rm\Rrightarrow (Difference)/(Original)* 100


\\ \rm\Rrightarrow (4.25)/(80)* 100


\\ \rm\Rrightarrow 0.0535(100)


\\ \rm\Rrightarrow 5.35\%
