Question

Цена ручки понизилась на 40%, а затем ещё на 25%. На сколько процентов понизилась цена ручки по сравнению с первоначальной? Сколько стал стоить товар если его первоначальная стоимость была 3000 рублей?

Answer 1

3000×40:100=1200
1200×25:100=300

Answer 2

Calculation of the Price Reduction

To calculate the final price of the pen after two successive reductions of 40% and 25%, we can use the following steps:

1. Apply the first reduction of 40% to the original price. 2. Apply the second reduction of 25% to the price obtained after the first reduction.

Let's calculate the final price step by step.

First Reduction of 40%

The first reduction of 40% means that the price of the pen is now 60% of its original price. To find the price after the first reduction, we can multiply the original price by 0.6.

Price after the first reduction = 0.6 * Original price

Second Reduction of 25%

The second reduction of 25% means that the price after the first reduction is now 75% of its value. To find the price after the second reduction, we can multiply the price after the first reduction by 0.75.

Price after the second reduction = 0.75 * (0.6 * Original price)

Calculation of the Final Price

To find the final price of the pen after both reductions, we need to simplify the expression obtained from the second reduction.

Final price = 0.75 * 0.6 * Original price

Now, let's calculate the final price using the given original price of 3000 rubles.

Final price = 0.75 * 0.6 * 3000 rubles

Calculating the expression, we find that the final price of the pen is 1350 rubles.

Therefore, the price of the pen has been reduced by 55% compared to its original price of 3000 rubles.
