How old is christopher now ?

Say Christopher's current age is x. That means Ishaan's current age is x + 20, because he's 20 years older.

14 years ago, Christopher was x - 14 years old. If Ishaan was 3 times as old, he was 3(x - 14) years old.

We know Ishaan's current age is 14 years more than his age 14 years ago, so we can say 3(x - 14) + 14 = x + 20

Using that equation, we can solve for x, which is Christopher's current age.

3(x - 14) + 14 = x + 20

3x - 42 + 14 = x + 20

3x - 28 = x + 20

2x = 48

x = 24

So, Christopher's current age is 24 years.
