In the figure given below, the rectangle represents the families of a housing society, and the three circles show the families that get their news from a newspaper, from television and from the radio. Each number is the number of families in that region.
How many families get their news from television and the radio but not from a newspaper?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 6
The required region must lie inside the Television circle and the Radio circle but outside the Newspaper circle.
Inside both the Television and Radio circles: 4 and 6
Of these, 4 also lies inside the Newspaper circle, so it is left out
Only 6 is inside the Television and Radio circles and outside the Newspaper circle
