if the price the of the item is decreased by 10% and then increased by 10% then net effect on the price of the item

• answer is::decrease b 1% ,100-10% of 100= 90,
  then 90+10% of 90= 99
  therefore, 100-99=1.

• let price is 100
  after decrement of 10% it will become 90
  then after 10 % increment it wil become
  (90 + 10% of 90)
  90+9=99
  i.e 1 percent decrement

• for this type of q's the formula is (x/10)^2 %decrease
  where x is given %
  eg: x=10 ,(10/10)^2= 1 % dec

• let the price be x.
  on decreasinf by 10% price will go from x to 9x/10.
  n den increasin by 10 den.price will nw become 99x/100.(9x/10 + 9x/100)
  so it will change by 1%.

• dec by 10%
  90%
  and then inc by 10%----100%
  net effect is (90+100)/2===95%

• let the price be 50
  after decreasing 10% means the price be 45 then after increased by 10% then the price will be49.5 so the loss be 50-49.5=.5

  10% dec=newer price=99
  total change =1%

• If a certain number is increased by x% then decreased by x% or vice versa, the net change is always decrease. This change is given by a simple formula −(x/10)2= −(10/10)2= −1%. Negitive sign indicates decrease.
