A father is 5 times as old as his son.In 4 years the sum of their ages will be 56.Find their present ages.

F = 5(s) //F = father, s = son

F + 4 + s = 56
5s + 4 + s = 56
6s + 4 = 56
6s = 52
s = 8 (approx)

Son = 8 yrs
Father = 40 yrs.

Check:
F = 5(s) = 5(8) = 40
S = 8

40+4 = 44
8+4 = 12

44+12 = 56.

Ah, the classic math puzzle! Let's clown around with some numbers, shall we?

Let's call the son's age x and the father's age y. According to the information given, we know that:

y = 5x (since the father is 5 times as old as the son)

In 4 years, their ages will be increased by 4. So, we can set up another equation:

(x + 4) + (y + 4) = 56

Now, let's substitute y with 5x from the first equation:

(x + 4) + (5x + 4) = 56

Combine like terms:

6x + 8 = 56

Subtract 8 from both sides:

6x = 48

Divide both sides by 6:

x = 8

Now, we can find the father's age:

y = 5x
y = 5 * 8
y = 40

So, the son is currently 8 years old, and the father is 40 years old. Ta-da!

Let's consider the present ages of the father and son as x and y, respectively.

According to the given information:
1) The father is 5 times as old as his son, so we can write the equation: x = 5y.
2) In 4 years, their ages will increase by 4, so we can write the equation: (x + 4) + (y + 4) = 56.

To find their present ages, we need to solve these two equations.

Substituting x from equation 1 into equation 2, we get:
(5y + 4) + (y + 4) = 56

Simplifying the equation:
6y + 8 = 56
Subtracting 8 from both sides:
6y = 48
Dividing both sides by 6:
y = 8

Substituting the value of y (son's age) into equation 1:
x = 5(8)
x = 40

Therefore, the father is 40 years old and the son is 8 years old.

To solve this problem, let's assume the son's current age is x years.

According to the problem statement, the father is 5 times as old as his son. This means the father's current age is 5 times x, which is 5x years.

In 4 years, the son's age will be x + 4, and the father's age will be 5x + 4. The sum of their ages at that time will be 56. So, we can write the equation:

(x + 4) + (5x + 4) = 56

Now, let's simplify the equation:

6x + 8 = 56

Subtract 8 from both sides:

6x = 48

Divide both sides by 6:

x = 8

So, the son's current age is x = 8 years, and the father's current age is 5x = 5 * 8 = 40 years.

Therefore, the son's present age is 8 years, and the father's present age is 40 years.
