Question

Answer 1

Given that Jack was 34 years old when his son Phillip was born. The sum of their age is now 50 years.

Let a be the present age of Jack's son.

The present age of jack is a+34

The sum of their age is 50.

$a+a+34=50$

$2a+34=50$$2a=50-34$

$2a=16$$a=\frac{16}{2}$$a=8$

The present age of Jack's son is 8 years.

The present age of Jack =8+34=42 years.

The present age of Jack is 42 years and his son's age is 8 years.
