Need an explanation.



Here,

For any percentage problem always compare with \(100\), for easy calculation

Let the price of the item = $\(100\)

Now, the price is increased by \(30\)%, the price of the item = \(100 * 1.3\)

Again price decreased by \(40\)% , the price of the item = \({100}*{1.3}*{0.6}\)

Final price = \({100}*{1.3}*{0.6} = 78\)

% Change = \(\frac{{100 -78}}{100}* 100 = 22\)%

The price paid by the employee was 22% below the original price
