Answer 3

Solution

Let's solve this step by step.

1. Let's assume the son's current age is represented by x. 2. According to the given information, the father is 30 years older than the son, so the father's current age is x + 30. 3. In 4 years, the father will be 4 times older than the son, so we can represent this as: x + 30 + 4 = 4(x + 4).

Now, let's solve for x.

Calculation

1. x + 30 + 4 = 4x + 16 (Expanding the equation) 2. 34 = 4x - x + 16 (Simplifying) 3. 34 = 3x + 16 (Combining like terms) 4. 34 - 16 = 3x (Subtracting 16 from both sides) 5. 18 = 3x (Simplifying) 6. x = 6 (Dividing both sides by 3)

So, the son is currently 6 years old.

Conclusion

The son is currently 6 years old.
