In the figure given below, the rectangle represents the 100 families of a village, and the three circles show the families that own a car, a scooter and a bicycle. Each number is the number of families in that region.
How many families own a car or a scooter (or both) but do not own a bicycle?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 51
The required families lie inside the Car circle or the Scooter circle but outside the Bicycle circle.
Car only: 18
Scooter only: 24
Car and scooter, no bicycle: 9
5, 4 and 8 are left out, as they lie inside the Bicycle circle; 20 lies outside the Car and Scooter circles
Total \(=18+24+9=51\)
