The ratio between the number of passengers traveling by I and II class between the two railway stations is 1 : 50, whereas the ratio of I and II class fares between the same stations is 3 : 1. If on a particular day Rs. 1,325 were collected from the passengers traveling between these stations, then what was the amount collected from the I class passengers?

A.Rs. 1250
B.Rs. 85
C.Rs. 75
D.Rs. 1000

Final answer:

To solve this problem, set up a system of equations using the given ratios of passengers and fares. Solve the equations to find the amounts collected from each class of passengers. The amount collected from I class passengers is closest to Rs. 1000.

Step-by-step explanation:

To solve this problem, we can set up a system of equations. Let's denote the number of passengers traveling by I class as x and the number of passengers traveling by II class as y. We are given the ratio between the two classes, which is 1:50. This can be written as x:y = 1:50.

We are also given the ratio of the fares between the two classes, which is 3:1. This can be written as the total amount collected from the passengers traveling in each class is in the same ratio. Let the amount collected from I class passengers be a and the amount collected from II class passengers be b. This gives us the equation:

a:b = 3:1

We are told that the total amount collected from all passengers is Rs. 1,325. This means that a + b = 1325.

We can use these two equations to solve for a and b. Let's first solve for a:

a:b = 3:1 ---> a/b = 3/1 ---> a = 3b

Substituting this into the equation a + b = 1325:

3b + b = 1325 ---> 4b = 1325 ---> b = 1325/4 ---> b = 331.25

So the amount collected from II class passengers is Rs. 331.25.

Now, we can find the amount collected from I class passengers:

a = 3b ---> a = 3(331.25) ---> a = 993.75

Therefore, the amount collected from I class passengers is Rs. 993.75, which is closest to Rs. 1000 (option D).
