In the following diagram, the triangle represents doctors, the circle represents players and the rectangle represents singers.
Which region represents the individuals who are players as well as singers but not a doctor?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → B
A region stands for the people of every shape it lies inside, and not for the shapes it lies outside. Players who are singers but not doctors must be inside the circle and the rectangle, and outside the triangle.
Region B lies inside the circle and the rectangle, to the left of the triangle. Region C is also inside the circle and the rectangle, but it lies inside the triangle as well, so its people are doctors too.
