Capgemini Company Numerical Ability Ratio and Proportion

The ratio between the number of passengers travelling by II & III Class AC between two railway stations is 1 : 20, whereas the ratio of the II & III Class fares between the same stations is 3 : 1. If on a particular day, Rs. 25300 were collected from the passengers travelling between these stations, what was the amount collected from the Class III passengers ?
A)Rs. 6600 B)Rs. 11000 C)Rs. 18300 D)Rs. 22000

Read Solution (Total 1)

Let no.of passengers travelling by II class AC = 1X and III class = 20X.
Similarly fare for II class = 3Y and III class = 1Y.
Sum of (No.of passengers × Fare for passengers) for both classes= total amount collected
So (1X × 3Y)+(20X × 1Y) = 25300
3XY+20XY = 25300
23XY = 25300
=> XY = 1100
Now amount collected for III class = 20×1100 = 22000.
