Question

Цену товара сначала снизили на 20 % , затем новую цену снизили еще на 15 % и , наконец после пересчета произвели снижение еще на 10 %. На сколько % всего снизилась первоначальная цена?

Answer 1

Пусть х цена товара , тогда    по условию
0.8x*0.85*0.9=0.612x 
то есть всего на 0,388-38,8%

Answer 2

Calculation of the Total Price Reduction

To calculate the total price reduction, we need to consider the initial price reduction of 20%, followed by an additional reduction of 15%, and finally a further reduction of 10%.

Let's assume the initial price of the product is $100.

1. Initial Price Reduction of 20%: - The initial price reduction of 20% would be 20% of $100 = $20. - After this reduction, the new price would be $100 - $20 = $80.

2. Additional Price Reduction of 15%: - The additional price reduction of 15% would be 15% of $80 = $12. - After this reduction, the new price would be $80 - $12 = $68.

3. Further Price Reduction of 10%: - The further price reduction of 10% would be 10% of $68 = $6.80. - After this reduction, the final price would be $68 - $6.80 = $61.20.

Therefore, the initial price of the product was reduced by a total of $100 - $61.20 = $38.80, which represents a percentage reduction of approximately 38.8%.

Please note that the above calculation assumes a linear reduction of percentages. If the reductions were applied in a different order or using a different method, the final result may vary.
