1. First you have to find a number evenly divisible by 3. That leaves 30 and 45. Five years ago the father was either 25 or 40. What do you think the answer is?

2. Which choices are evenly divisible by 4? Which answer do you think is right?

1.

Let the son's present age be x

then the father's present age is 3x

Five years ago :

son's age = x-5

father's age = 3x-5

so

x-5 + 3x-5 = 30

4x = 40

x = 10

So the son is now 10 and the father is now 30

Now you do #2 the same way.
