I am preparing for an olympiad and came across the following question in a workbook. There is answer but no explanation:
The ratio between the number of passengers travelling by Ist and IInd class between two railway stations is 1:50, whereas the ratio of Ist and IInd class fares between the same stations is 3:1.If on a particular day, Rs. 1325 is collected from the passengers travelling between these stations by these classes, then what was the amount collected from the IInd class passengers?
(A)Rs.750 (B)Rs.850 (C)Rs.1000 (D)Rs.1250
I want to know the explanation to the answer.
Note:Rs. stands for INR(Indian Rupee) which is the currency of India
