instead of multiplying a number by 5 , the number is divided by 10 . what is the percentage of error obtained ?
"let the number be x the right number is 5 x the wrong number is x / 10 error is ( 5 x - x / 10 ) = 49 x / 10 percentage of error is ( ( 49 x / 10 ) / 5 x ) * 100 = 98 % answer : b"
subtract(const_100, multiply(divide(divide(10, 10), multiply(5, 10)), const_100))
