Read details carefully for questions in the following figure, the triangle represents teachers, the circle represents students and the rectangle represents actors.
Which number represents teachers who are actors but not students?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 6
Teachers who are actors lie where the triangle and the rectangle overlap; “not students” leaves out the part inside the circle. That is the region marked 6 (shaded below).
