Question

Два кондитера украсили 306 тортов. Первый кондитер работал 4 часа, а второй 5 ч. Сколько тортов украсил каждый кондитер, если они работали с одинаковой скоростью?

Answer 1

Ответ:

306 / (5+4) = 34 в час

5*34 = 170 второй кондитер

4*34 = 136 первый кондитер

Problem Analysis

We are given that two confectioners decorated a total of 306 cakes. The first confectioner worked for 4 hours, and the second confectioner worked for 5 hours. We need to determine how many cakes each confectioner decorated if they worked at the same speed.

Solution

To solve this problem, we can set up a proportion based on the number of cakes decorated and the time worked by each confectioner.

Let's assume that the first confectioner decorated x cakes, and the second confectioner decorated y cakes.

According to the given information, we have the following proportions:

x cakes / 4 hours = y cakes / 5 hours

We can cross-multiply and solve for x and y.

Calculation

Cross-multiplying the proportion, we get:

5x = 4y

To find the values of x and y, we need to find a pair of numbers that satisfy this equation and add up to 306.

Let's start by finding a pair of numbers that satisfy the equation:

5x = 4y

We can try different values of x and find the corresponding value of y:

- If x = 4, then y = 5. - If x = 8, then y = 10. - If x = 12, then y = 15. - If x = 16, then y = 20. - If x = 20, then y = 25.

We can see that when x = 20 and y = 25, the equation is satisfied.

Now, we need to check if the sum of x and y is equal to 306:

20 + 25 = 45

Since 45 is not equal to 306, the values of x and y we found are not correct.

Let's try another pair of numbers:

- If x = 40, then y = 50.

Checking the sum:

40 + 50 = 90

Since 90 is not equal to 306, the values of x and y we found are not correct.

We can continue this process until we find a pair of numbers that satisfy both the equation and the sum condition.

Answer

Based on the calculations, we cannot determine the exact number of cakes each confectioner decorated if they worked at the same speed. The given information does not provide enough information to solve the problem.
