1500 attended, and x are from town A
=> 1500-x people attended the marathon who are not from town A;
z participated in the marathon who are not from town A
hence those who did not participate and not from town A
= \((1500-x)\) -z
Option E
=> 1500-x people attended the marathon who are not from town A;
z participated in the marathon who are not from town A
hence those who did not participate and not from town A
= \((1500-x)\) -z
Option E
