Answer:
24 years
Step-by-step explanation:
Let Christopher's age=c
Since Christopher is 20 years younger than Ishaan.
Ishaan's age=c+20
Fourteen years ago, Ishaan was three times as old as Christopher.
Their ages 14 years ago are:
For Christopher: c-14
For Ishaan: (c+20)-14
Therefore:
3(c-14)=c+6
3c-42=c+6
3c-c=6+42
2c=48
Divide both sides by 2
c=24
Christopher is 24 years old.
