Question
In a village, 40% of the families have bikes, 10% have
cars and 10% have both bikes and cars. There are 60 families in the village. How many families have neither bikes nor cars?Solution
ATQ,
Total families = 60. 40% have bikes = 24 families. 10% have cars = 6 families. 10% have both = 6 families. Families with either bikes or cars = 24+6−6=24. Families with neither bikes nor cars = 60−24=36. So, 36 families have neither bikes nor cars.
