AFCT Arithmetic Reasoning Test 2025 – 400 Free Practice Questions to Pass the Exam

To determine how many members remain in the group after 3 leave, you would start with the total number of members, which is 15. From this total, you subtract the number of members who left, which is 3. The calculation would look like this:

15 (original members) - 3 (members that left) = 12 (remaining members).

This clearly indicates that after 3 members leave the group, there are 12 members still remaining. Thus, the correct answer is that there are 12 members left in the group. This reasoning is based entirely on basic subtraction and ensures that you have accounted for the members who departed from the original count.
