Question
In a city, the number of persons travelling by bike is
70% the number of persons travelling by metro. The number of persons travelling on foot is 50% the number of persons travelling by bike. If 500 persons travel by metro, then how many persons travel on foot?Solution
Number of persons travelling by bike = 500 × (70/100) = 350 Number of persons travelling by walk = 350 × (50/100) = 175
