The cost of apples is increased by 20% and then decreased by 20%, What is the net percentage decreases ?

4 %

Let Initial Price = 100x

ATQ

Price increase by 20%, then decrease by 20%

Therefore,

New Price = 100x × \(\frac{120}{100}\) × \(\frac{80}{100}\)

               = 100x × \(\frac{6}{5}\) × \(\frac{4}{5}\)  = 96x

Loss = 100x - 96x = 4x

Loss % = \(\frac{4x}{100x}\) × 100 = 4%
