Daniel.

Answer 1

Answer: Daniel's age = 8

Step-by-step explanation: Kevin is 3 times as old as Daniel. 4 years ago, Kevin was 5 times as old as Daniel. How old is Daniel now?

Kevin's age = 24 Daniel's age = 8.

Answer 2

Explanation:

Let's use algebra to solve the problem.

Let's say Daniel's age now is "D".

According to the problem, Kevin's age is 3 times as old as Daniel:

K = 3D

And four years ago, Kevin was 5 times as old as Daniel:

K - 4 = 5(D - 4)

We can substitute the first equation into the second equation:

(3D) - 4 = 5(D - 4)

Simplifying:

3D - 4 = 5D - 20

Subtracting 3D from both sides:

-4 = 2D - 20

Adding 20 to both sides:

16 = 2D

Dividing by 2:

D = 8

So Daniel is currently 8 years old.

To find Kevin's age, we can substitute D = 8 into the first equation:

K = 3D = 3(8) = 24

So Kevin is currently 24 years old.
