Download Solution PDFGiven:
The price of an article is increased by r%.
The new price was decreased by r% later.
Now the latest price is Rs. 1.
Concept used:
If the price of an article is increased by r% and then decreased by r% , the total decrease is r2/100
Calculation:
Let the old price be Rs x
As per the question,
\(x - \frac{r^2}{100} \times \frac{x}{100}\) = 1
⇒ x = \(\rm\frac{10000}{10000−r^{2}}\)
∴ The correct option is 1
