Answer 1

1) После того как израсходовали 75% полученных денег, осталось 355 руб. Сколько денег было получено?

To find out how much money was received, we can set up an equation using the given information. Let's assume the total amount of money received is "x" rubles.

According to the problem, after spending 75% of the received money, there is 355 rubles left. This can be expressed as:

x - 0.75x = 355

Simplifying the equation:

0.25x = 355

To solve for x, we divide both sides of the equation by 0.25:

x = 355 / 0.25

Evaluating the expression:

x = 1420

Therefore, the amount of money received was 1420 rubles.

2) По плану рабочий должен был изготовить на смену 150 деталей, но изготовил 180 деталей. На сколько процентов рабочий перевыполнил план?

To find out the percentage by which the worker exceeded the plan, we can use the following formula:

Percentage = (Excess / Plan) * 100

In this case, the plan was to manufacture 150 parts, but the worker manufactured 180 parts. The excess can be calculated as:

Excess = Actual - Plan = 180 - 150 = 30

Substituting the values into the formula:

Percentage = (30 / 150) * 100 = 20%

Therefore, the worker exceeded the plan by 20%. ***
