If the price of article is decreased by 10% ,then increased by 10%,the net effect on the price of the item is?

• Suppose the price of article be 100 rupees and now decreased by 10% would make it Rs 90 and the when increased by 10% , it will be 99% .. So a net of 100-99% would make an overall decrease of 1% on the article.
  Note: Take the price as 100 only because percentage can be calculated on it easily and correctly

• increased by x%
  decreased by x%
  price item always= ((x*X)/100 ) % decrease
  so
  ans= 100/100 = 1 % decrease

• there will be a loss of 1%
  formula= when % of loss and gain on same thing is same = (x/10)^2

• Net price will be 99% of initial price.
  100*0.9*1.1= 99

• let the initial price be 100, when decreased by 10% it'll be 90, & then increased by 10% so it becomes 90+9=99(as 10% of 90 is 9, and then 100-99=1% so ANS 1% decrease on net price

• this is a successive percent case. a+b+(ab/100)
  -10+10-1 =1% decrease

• (x/10)^2 ie (10/10)^2 which gives 1

• if x=100
  10% decrease =90
  again 10% increase=99%
  so,the price of the amt is 1% decrease

• ex 100 decresed by 10% is 90
  10% of 90 is 9
  and 9 is added to 90 as it is increased... therefore 1% decrease in price

• assume the price as x.
  increased by 10% i.e, 10/100=0.1 => x+0.1 again decreased by 10% .
  so, net value will be x+0.1-0.1=x itself so there will be no change in the price of item.

• successive percent case. x+y+(xy/100)
  -10 + 10-1 =1% decrease

• This type of questions can be easily explained by using the following example :
  consider the amount to be 100
  so decrease by 10 % means = 100 - 10 = 90
  and now increasing 10 % means , 90 + 9 = 99
  that means , there is a total decrease by 1 % :)

• let price be 100
  now decrease in price by 10%=90
  again, increase by 10%=99
  hence price decrease by 1%

• use the formulea
  a+b+(ab/100)
  given a=-10%
  and b=+10%
  -10+10-100/100
  -1%
  minus indicates decreases by 1%

• always consider 100%is equal to 100 then item price=100;
  decreasing 10%first in 100% is means now item cost=90;
  agian increases means 90*10/100=9 then item cost=99;
  the net effect=100-99=1%dec
  
• 8 years agoHelpfull: Yes(0) No(0)
• 100--(10%dec)--90--(10%inc)--99
  net effect= (100-99)/100*100%
  =1%

• for example price is 100rs then by decreaing 10% we get 90 and then increasing by 10% it becomes 99. so there will be loss of 1 rupee. there will net loss of 1%.

• BY FORMULA:
  net effect=(+-a)+(+-b)+[(+-a)(+-b)]*100
  where + for increase and - for decrease
  i.e
  10-10-10*10/100=-1
  so 1% decrease
