A number is mistakenly divided by 5 instead of being multiplied by 5. Find the percentage change in the result due t this mistake.

(a)96% (b)95% (c)2400% (d)200%

• lets take a number 20
  20/5 = 4
  20*5 = 100
  
  diff = 100 - 4 = 96 %

• let assume it is x
  then after dividing by 5 number will x/5
  and after multiplying by 5 number will 5x.
  so our correct value is 5x apply formula
  Percentage Error = ((True value - False Value)*100)/True Value
  = ((5x-x/5)*100)/5x
  = (24x*100)/25x
  = 96

• let the no be y ,
  
  so after multiplied by 5 the no will be 5y but instead it is divided so the no is y/5 .
  so the difference is 5y-y/5= 24y/25
  therefore %age error is 24y/25 / y X 100% = 96%.
  so ans (a) 96 %

• let no be 1
  divided by 5 ->.2
  multiplied by 5->5
  change in result ->4.8
  %-age->(4.8/5)*100=96%

• lets take number 100
  100/5=20
  100*5=500
  then net error-> 500-20=480
  so (480/20)*100
  ans = 2400/%
