Question

Шла по улице семья крокодилов дед, два отца да два сына. всем вместе было 90 лет. сколько крокодилов шло по улице? сколько лет каждому, если каждый отец старше своего сына на 25 лет?

Answer 1

Их всего трое:дед, отец и сын
возраст - пусть самому младшему х лет, тогда
х+х+25+х+50=90
3х+75=90
3х=15
х=5 - самому младшему
х+25=30 - среднему
30+25=55 - самому старшему

Answer 2

Calculating the Number of Crocodiles and Their Ages

To solve this riddle, we can use algebraic equations to represent the relationships between the ages of the family members. Let's denote the age of the grandfather as G, the age of the first father as F1, and the age of the second father as F2. The age of the first son will be S1, and the age of the second son will be S2.

We are given the following information: 1. The sum of their ages is 90. 2. Each father is 25 years older than his son.

Solving for the Number of Crocodiles and Their Ages

Let's represent the given information in the form of equations: 1. G + F1 + F2 + S1 + S2 = 90 2. F1 = S1 + 25 3. F2 = S2 + 25

Now, we can use these equations to solve for the ages of the family members and the number of crocodiles.

Solution

Using the given information and the equations, we can solve for the ages of the family members and the number of crocodiles:

1. G + F1 + F2 + S1 + S2 = 90 2. G + (S1 + 25) + (S2 + 25) + S1 + S2 = 90 3. G + S1 + 25 + S2 + 25 + S1 + S2 = 90 4. G + 2S1 + 2S2 + 50 = 90 5. G + 2S1 + 2S2 = 40

Given the information, we can't determine the exact number of crocodiles and their ages without additional details. If you have any other information or if there's anything else you'd like to discuss, feel free to ask!
