Explanation:
The first sentence is not very clear. “more than the age his son’s age” I am interpreting as meaning 5 years older than his son. If we are talking about humans, a five year old cannot father a child and so cannot be only five years older than his son. If you are talking about some animal, dogs, for example, the solution would be like this:
Let F be the father’s age and S be the son’s age. From the first statement:
F=S+5
From the second statement:
F+7=3*(S+7)
Substituting the first equation into the second we get:
S+5+7=3*(S+7)
Solving for S
S+12=3*S+21
3*S-S=12–21
2*S=-9
S=-4.5
F=S+5=0.5
So the Father is 6 months old and the Son will not be born for another four and a half years. In 7 years, father will be 7 1/2 and the son will be 2 1/2 which is one third of the father’s age as the problem requires.
