Answer:
Brett is 62 years old, Carl is 70 years old and Mark is 80 years old.
Step-by-step explanation:
let the age of Brett be x years.
thus the age of Mark is (x+18) years .
{as it is given that Brett is 18 years younger than Mark}
∴ Age of Carl is (x+8) years .
Now the sum of ages,
3x+26=212 (given)
3x=186
∴x=62
thus , the age of Brett is 62 years , the age of mark is (x+18)= 80 years and the age of Carl is (x+8)= 70 years
