If the price of a washing machine is first increased by 25% and then decreased by 25%, then the net change in price will be a :

6.25% increase 6.25% decrease 6.5% increase 6.5% decrease

6.25% decrease

Net change in percentage = +A% - B% - \(\frac{AB }{100}\)% = +25% - 25% - \(\frac{25 ×  25  }{100}\)% = - 6.25% = 6.25% decrease
