- 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% - 13 years agoHelpfull: Yes(8) No(0)
- % error= (actual value- wrong value)/actual value *100
so error%= (7x-x/7) / 7x *100
=4800/49
=97.9% - 9 years agoHelpfull: Yes(1) No(0)
