instead of multiplying a number by 3 , the number is divided by 5 . what is the percentage of error obtained ?
"let the number be x the right number is 3 x the wrong number is x / 5 error is ( 3 x - x / 5 ) = 14 x / 5 percentage of error is ( ( 14 x / 5 ) / 3 x ) * 100 = 93.33 % answer : d"
subtract(const_100, multiply(divide(divide(5, 5), multiply(3, 5)), const_100))
