Question

In a city 20% of the population travels by car, 50% travels by bus and 10% travels by both car and bus. Then, persons traveling by car or bus are ________.
​

Answer 1

Let x be the total number of population

then according to the problem,

p(car)=20% of x=x/5

p(bus)=50% of x=x/2

p(car ∩ bus)=10% of x=x/10

since,

p(car ∪ bus)=p(car)+p(bus)-p(car ∩ bus)

p(car ∪ bus)=x/5 + x/2 - x/10=3x/5 persons ans.

if x(population)=100

Then persons travelling by car or bus will be 60 persons.
