Question

The price of an article is increased by 25%. By how much per cent, should this new male be decreased to restore it to its former value?

Answer 1

Let the price of article be Rs. Y

If the price of an article is increased by 25%

The new price = Y + (Y × 25)/100 = 5y/4

To restore its former value the new price must be decreased by = \(\frac{\frac{5y}{4}-y}{\frac{5y}{4}}\) \(\times 100\) =20%
