instead of multiplying a number by 5 , the number is divided by 5 . what is the percentage of error obtained ?
"let the number be x the right number is 5 x the wrong number is x / 5 error is ( 5 x - x / 5 ) = 24 x / 5 percentage of error is ( ( 24 x / 5 ) / 5 x ) * 100 = 96 % answer : c"
subtract(const_100, multiply(divide(divide(5, 5), multiply(5, 5)), const_100))
