The price of an article was increased by p%. Later the new price was decreased by p%. If the latest price was Re. 1, the original price was :

a. Re. 1
b. Rs. (1 - p2 / 100)
c. Rs. (10000 / 10000 - p2)
d. Rs. (√1 - p2 / 100)

• If ooriginal price was x, then
  x* (1+p/100)*(1-p/100) =1
  x*(1-p^2/10000) =1
  x*((10000-p^2)/10000
  x= Rs. (10000 / (10000 - p2)) .. option C
