Instead of multiplying a number by 7, the number is divided by 7. What is the percentage of error obtained ?

• let the number be x
  the right number is 7x
  the wrong number is x/7
  error is(7x-x/7)=48x/7
  percentage of error is((48x/7)/7x)*100=97.959%

• % error= (actual value- wrong value)/actual value *100
  so error%= (7x-x/7) / 7x *100
  =4800/49
  =97.9%
