• Friend in this typo questions when rate is same their will be loss of (R^2)/100...so 1%loss
• 11 years agoHelpfull: Yes(13) No(1)
• the funda is simple , there will always be loss whenever there is successive % decrease and % increase in the price (provided that % value be same ).
  
  so loss % =(%value)^2/100
  
  To understand it in a better way just use PCG(Percantage Chnage Graph) rule

• Let the price be 100
  now 100*10/100=10
  100-10=90 is the price of an item which is decreased by 10%
  now 90*10/100=9
  90+9=99 is the price of an item which is increased by 10%
  the net effect on the price of the item is 100-99=1
  hence it is decreased by 1%

• lt the price is 100 thn aftr 10% decrease the price will be 100-100*10/100= 90, aftr 10 % increase the price will be 90+90*10/100=99. thrfor the net effect is 100-99=1 i.e 1%

• let price be 100
  Decreased by 10%=> 100-100(.1)=90
  Increased by 10%=> 90+90(.1)=99
  therefore the price is reduced by 1%

• X% decrese X% increse then formula -X2/100...(100)/(100)=-1%...- represents decrese...

• use a formula to solve these type of questions- x+y+xy/100 means 10-10-100/100=-1 here decrease by 1% here (-) is used for decrease

• [(+10*-10)/100]+(+10-10)=-1
  so 1% decrease

• assume x
  x=100
  decrease by 10%
  x=90
  increase by 10%
  x=99
  so ans=decrease by 1%
• 11 years agoHelpfull: Yes(1) No(0)
• ans is decreased by 1%
  As loss%=(x/10)^2; where x is common loss or gain percentage.
  Here, x=10% ; so loss%=(10/10)^2=1%

• let price be 100 with increase of 10% it becomes 110
  again decrease of 10% on 110 it becomes 110-11=99
  so,net effect decrease of 100-99=1%
