Question

Из 523 цыплят, выведенных в инкубаторе, петушков оказалось на 25 меньше, чем курочек. Сколько курочек и сколько петушков было выведено в инкубаторе?

Answer 1

Х петушки
х+25 курочки
х+х+25=523
2х=498
х=249 петушки
249+25=274 курочки

Answer 2

Calculating the Number of Chicks

To solve this problem, we can use a system of equations. Let's denote the number of chicks as C, the number of roosters as R, and the total number of chicks and roosters as 523. We are given that the number of roosters is 25 less than the number of hens, so we can express this as an equation: R = C - 25.

We also know that the total number of chicks and roosters is 523, so we can express this as another equation: C + R = 523.

Solving the System of Equations

We can solve this system of equations to find the values of C and R.

Substituting the value of R from the first equation into the second equation, we get:

C + (C - 25) = 523

Solving for C: 2C - 25 = 523 2C = 523 + 25 2C = 548 C = 548 / 2 C = 274

Now that we have the value of C, we can find the value of R: R = C - 25 R = 274 - 25 R = 249

Conclusion

So, there were 274 chicks and 249 roosters hatched in the incubator.
