1,500 individuals attended a marathon held in Town A. Of those, only y participated in the marathon. If x of the 1,500 individuals were from Town A, and z of the individuals participated in the marathon but were not from Town A, which of the following represents the number of individuals who did not participate in the marathon and were not from Town A?
A. 1,500 - x + 2y
B. 1,500 - x + 2z
C. 1,500 - x - y + z
D. 1,500 - x - y - z
E. 1,500 - x - z
The OA is E.
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.
Has anyone another strategic approach to solve this PS question? Regards!
