In the figure given below, the triangle represents tennis players, the upper rectangle represents doctors and the lower rectangle represents Indians. Each number is the number of people in that region.

How many doctors are Indians but not tennis players?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 9
The required region must lie inside both rectangles (doctors and Indians) but outside the triangle (tennis players).
Inside both rectangles: 10 and 9
Of these, 10 also lies inside the triangle (these doctors play tennis), so it is left out
Only 9 is inside both rectangles and outside the triangle
